dc.description.abstractPhotoluminescence (PL) behavior of SrBi2Nb2O9 (SBN) powders was explained by means of beta-Bi2O3 phase on the SBN lattice. Oxygen vacancies and recombination of electrons holes in the valence band lead to the formation of [NbO5 center dot V-O(x)], [NbO5 center dot V-O(center dot)] and [NbO5 center dot V-O(center dot center dot)] complex clusters which are the main reason for the PL at room temperature. X-ray diffraction and Fourier transform Raman spectroscopy were used as tools to investigate the structural changes in SBN lattice allowing to correlate [NbO5 center dot V-O(center dot)]/[NbO6](') ratio with the evolution of the visible PL emission in the SBN powders.
