Zinc oxide ceramics have been prepared from ZnO powders obtained by mechanical
milling for 300 min in air in different high-energy mills. Structural disorder induced in
ZnO powder by mechanical activation (MA) and partial structural ordering observed
after proposed thermal treatment (TT) in ZnO ceramic has been characterized by XRD
and Raman spectroscopy. The influence of defect creating during MA and TT on optical
and electronic properties of ZnO has been analyzed using spectroscopic ellipsometry and
photoluminescence spectroscopy. It was found the strong influence of intrinsic and
extrinsic defects on band-gap widening and change in PL spectra shape and intensity.
