AB  - The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, with the amount of spinel phase increasing with increasing Zn content. Scanning electron microscopy analysis combined with energy dispersive X-ray spectroscopy showed that the Zn-bearing phase occurred in the form of individual spinel ZnFe2O4 grains in a hematite matrix. DC conductivity was measured in the temperature range 25-225°C (298-498 K). Impedance spectroscopy measurements in the same temperature range were carried out in the frequency range 100Hz to 10 MHz. Increase in the Zn content resulted in increased electrical conductivity and higher values of the dielectric constant. The resistance and capacitance of grains and grain boundaries were analyzed by modeling the experimental results using an equivalent circuit.

AB  - PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, and optical parameters were calculated. Local impurity modes of boron were observed at about 150 and 240 cm(-1). For all samples, after FIR measurements, the content of boron was measured using inductively coupled plasma atomic emission spectrometry. Optical mobility of free carriers was calculated and it was the highest for the sample with only 0.014 at.% of boron in PbTe. A negative photoconductivity effect at 130 K for PbTe + B was also observed.

AB  - Far infrared reflection spectra measured at room temperature were used to investigate vibrational properties of PtSb2 single crystals. The experimental results were analyzed using a dielectric function taking into account the existence of plasmon-ionised impurity-phonon interactions. Together with strong coupling three infrared active lattice modes at about 143, 187 and 202 cm(-1) were observed. These results were discussed with respect to calculated literature vibrational frequencies. Electrical properties of single crystal PtSb2 were also measured at room temperature.

AB  - Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide frequency range (100 Hz to 10 MHz) at different temperatures. The real and the imaginary part of the complex impedance traced semicircles in the complex plane. The resistance and the capacitance of bulk and grain-boundary regions were determined by modeling the experimental results using several equivalent circuits taking into account bulk deep trap states. Admittance complex diagrams were also determined in order to understand better the conduction mechanisms occurring in the polycrystalline Zn2SnO4-SnO2 system.

Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 at.%, 0.7 at.% and 1.1 at.% Cr are presented and numerically analyzed. Local modes were determined at about 260 cm(-1) and 480 cm(-1) for PbTe doped with Cr and at slightly higher frequencies for PbSnTe doped with Cr. The origin of the local modes was discused about the possible application of the PbSnTe + Cr alloys.

AB  - ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures were then mechanically activated for 10 minutes in a planetary ball mill, uniaxially pressed and sintered at 1300°C for 2h. The phase composition of the sintered samples was determined with X-ray Diffraction (XRD) analysis and a detailed Rietveld analysis was performed. Room temperature far infrared reflectivity diagrams were obtained using Bruker 113V FTIR spectrometer and fitted with several theoretical models in other to determine parameter values for some structural and optical properties of the obtained material.

AB  - Single-phase zinc-stannate thin films of different thickness values were prepared by radio frequency magnetron sputtering on a silica substrate. Rietveld analysis of X-ray diffraction data confirmed that the films had an inverse spinel structure, with a cation inversion parameter of 0.8. Room temperature far and mid infrared reflectivity spectra were measured in the range 50-4000 cm(-1). The reflectivity diagrams were analyzed using the four-parameter model of coupled oscillators for optical phonons with a standard multi-layer technique taking into account the thin-film layer and the substrate. The optical parameters were determined for seven oscillators belonging to the spinel structure. Their origin was discussed in relation to non-stoichiometry of the thin film and cation disorder in the crystal lattice. Bom effective charges were calculated from the transversal/ longitudinal splitting.

AB  - The effects of Bi2O3 addition on the phase composition, microstructure and optical properties of ZnO-SnO2 ceramics were investigated. Starting powders of ZnO and SnO2 were mixed in the molar ratio 2:1. After adding Bi2O3 (1.0 mol.%) this mixture was mechanically activated for 10 min in a planetary ball mill, uniaxially pressed and sintered at 1300 degrees C for 2 h. Far-infrared reflection spectra were measured (100-1000 cm(-1)). To investigate the occurred differences in FTIR spectra, the Bi2O3-doped sample was examined more carefully with a Perkin-Elmer FTIR spectrometer (Perkin Elmer, Waltham, MA, USA) connected with a Perkin-Elmer FTIR microscope and itemized points of interest were also studied with SEM-EDS.

AB  - Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface area, pore volume and pore size distribution spectra of mechanically activated powder mixtures were established by N-2 adsorption at 77 K. Microstructure analysis was performed using scanning electron microscopy (SEM) and digital pattern recognition (DPR) microstructure quantity analysis. The phase composition of the mixed powders was determined by Xray analysis. Mechanochemical activation of the ZnO-SnO2 system resulted in fine grinding of the starting particles and generation of contacts between them, mass transfer at contacts zones and formation of Zn2SnO4 spinel, which was observed after 40 min of activation.

AB  - Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered up to 1200 degrees C with a heating rate of 5 degrees C/min. X-ray diffraction analysis of obtained powders and sintered samples was performed in order to investigate changes of the phase composition. The microstructure of sintered samples was examined by scanning electron microscopy. The photoacoustic phase and amplitude spectra of sintered samples were measured as a function of the laser beam modulating frequency using a transmission detection configuration. Fitting of experimental data enabled determination of photoacoustic properties including thermal diffusiviiy. Based on the results obtained a correlation between thermal diffusivity and experimental conditions as well the samples microstructure characteristics was discussed.

AB  - A mixture of starting ZnO and SnO2 powders (molar ratio 2: 1) were mechanically activated for 10, 40, 80 and 160 min in a planetary ball mill and then isothermally sintered at 1300 degrees C for 2 h in order to obtain Zn2SnO4 ceramics. X-ray diffraction analysis confirmed single-phase polycrystals. Far infrared reflection spectra were measured (100-1400 cm(-1)). The same oscillators were observed, but the highest intensity of reflectivity peaks was obtained for the powder activated 10min and it gradually decreased with longer times of mechanical activation. This is in agreement with microstructure analvsis where longer times of mechanical activation lead to increased porosity and defects. Using group theory six ionic oscillators were calculated for single crystal Zn2SnO4 Spectra, but two more oscillators were observed in the obtained experimental spectra, which Could be the result of mechanical activation and sintering. The FIR experimental results were numerically analyzed and oscillator parameters were calculated.

Starting powders of ZnO and SnO2 were mixed in the molar ratio 2:1. After adding Bi2O3 this mixture was mechanically activated for 10 minutes in a planetary ball mill, uniaxially pressed and sintered at 1300 degrees C for 2h. The phase composition of the sintered samples was analyzed by X-Ray Diffraction (ARD) and by Energy Dispersive Spectrometer (EDS). Morphologies were examined by Scanning Electron Microscopy (SEM). An ImpedancelGain Phase Analyzer (HP 4194A) was used to measure the impedance spectra (100Hz - 10MHz) at different temperatures. The electrical DC resistivity/conductivity at different temperatures was measured using a High Resistance Meter (HP 4329A).

AB  - Room temperature far infrared reflectivity spectra of single phase spinel zinc-stannate thin films, prepared by rf magnetron sputtering on a glass substrate, and bulk sintered samples were measured. The sintered samples were obtained by mechanical activation of starting ZnO and SnO2 powders for 10 min followed by sintering at 1300 degrees C for 2 h. The reflectivity diagrams obtained for bulk samples were numerically analyzed using the four-parameter model of coupled oscillators. The optical parameters were determined for six observed ionic oscillators belonging to the spinel structure and two additional oscillators originating from the sintering procedure resulting from pores and grain boundaries. The reflectivity diagrams obtained for thin film samples were analyzed using the four-parameter model for optical phonons with a standard optical multi-layer technique.

abstract = "Room temperature far infrared reflectivity spectra of single phase spinel zinc-stannate thin films, prepared by rf magnetron sputtering on a glass substrate, and bulk sintered samples were measured. The sintered samples were obtained by mechanical activation of starting ZnO and SnO2 powders for 10 min followed by sintering at 1300 degrees C for 2 h. The reflectivity diagrams obtained for bulk samples were numerically analyzed using the four-parameter model of coupled oscillators. The optical parameters were determined for six observed ionic oscillators belonging to the spinel structure and two additional oscillators originating from the sintering procedure resulting from pores and grain boundaries. The reflectivity diagrams obtained for thin film samples were analyzed using the four-parameter model for optical phonons with a standard optical multi-layer technique.",

AB  - In this paper the changes that occurred in differently activated ZnO-SnO2 and sintered samples were investigated using photoacoustic spectroscopy. ZnO and SnO2 powders, mixed in the molar ratio 2:1, were mechanically activated in a planetary ball mill for 10-160 min. The mixtures were pres­sed and isothermally sintered at 1300 °C for two hours. X-ray diffraction analysis of the obtained sintered samples was performed in order to investigate changes of the phase composition and confirmed only the presence of a pure zinc stannate (Zn2SnO4) phase in all the sintered samples as a result of the solid state reaction and reaction sintering between the starting ZnO and SnO2 powders. The microstructure of the sintered sam­ples was examined by scanning electron microscopy and showed that mechanical activation leads to the formation of a structure with reduced particle size which accelerates spinel formation. Grain growth of the spinel phase slows down the densification process and together with the agglomerates formed during mechanical activation causes the appearance of a porous microstructure. The photoacoustic (PA) phase and amplitude spectra of the sintered samples were recorded as a function of the chopped frequency of the laser beam used (red laser with a power of 25 mW, λ=632 nm) in a thermal-transmission detection configuration. PA experimental data were analyzed using the Rosenzweig-Gersho thermal-piston model, which enabled determination of the thermal diffusivity DT (m2s-1), diffusion coefficient of the minority free carriers D (m2s-1) and the optical absorption coefficient (m-1). The detected differences of the measured thermal-electrical properties of the obtained Zn2SnO4 ceramics indicate changes in the material induced by the different preparation procedure of the starting powders before the sintering process.

AB  - Thin films of single-phase zinc-stannate (Zn2SnO4) were grown by rf magnetron sputtering onto glass substrates. Transmission in the visible range was measured allowing determination of the energy gap and thickness of analyzed thin film samples using interference fringes. The photoacoustic phase and amplitude spectra of all samples were measured as a function of the laser beam modulating frequency using a transmission detection configuration. Fitting of experimental data enabled calculation of thermal diffusivity, the coefficient of minority carrier diffusion, their mobility and lifetime.
