Ca1-xZrO3:xEu3+ (x = 0.05) phosphors have been prepared by using the low temperature solutioncombustion synthesis. The prepared nano phospors are well characterized by powder X-ray diffraction,scanning electron microscopy, Fourier infrared spectroscopy and transmission electron spectroscopy.PXRD results showed orthorhombic phase and SEM images showed porous agglomerated morphology.Influence of nitridation on structural and photoluminescence properties of the phosphor wereinvestigated for wide range of nitridation time. The photoluminescence (PL) intensity was found to varywith nitridation with small shift in the photoluminescence emission peaks. The probable reasons for thevariation of photoluminescence with nitridation are discussed.
