AB  - In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-
nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated.
Uniform nanopowders were synthesized by precipitation reaction followed by
centrifugation and systematically characterized by XRD, FTIR, SEM–EDS, TG and PL
methods. XRD analysis revealed the formation of hexagonal FAp crystals, and FTIR spectra
indicate the presence of nitrate (
NO3
−) and carbonate (
CO3
2−) species. SEM analyzes
confirm agglomerates composed of irregular nanometer-sized spheres. Emission of FAp
nanopowder occurred in the violet-blue region of the visible part of the spectrum, with
redshift to the blue-green color region when Pr3+,
NO3
− and CO3
2− co-doped in the lattice.
Analysis of luminescence spectra by MCR-ALS method extract three fluorophores from
the PrNCFAp sample and showed simultaneous existents of emission-reabsorption-emission
between dopants in FAp lattice. Antibacterial activity against pathogen Staphylococcus
aureus was investigated before and after treatment of nanopowders by UVA radiation
of 365 nm. Nanopowders irradiated with UVA compared to non-irradiated reduced Staphylococcus
aureus by 84.9% for PrNCFAp and 33.3% for FAp in the first 0.5 h of contact, and
76.1% and 42.9% after 24 h of contact. In addition, the obtained luminescent nanomaterials
showed a low degree of hemolytic activity and could potentially be candidates for further
research in dentistry.
