The effects of zinc on the zinc-doped CaTiO 3 :Pr 3 + phosphors have been investigated by varying the zinc concentrations from 0 to 100 mol%. The variation of zinc concentration influences the crystallinity and morphology of the phosphors. The crystallinity and PL intensity increase as zinc content
## Abstract Photoluminescence (PL) of thallium coโdoped with KCl~0.5~Br~0.5~:Eu^2+^ powder phosphors display emission bands at 320 and 370ย nm attributable to centres involving Tl^+^ ions in addition to characteristic Eu^2+^ emission around 420ย nm. Additional PL excitation and emission bandS observe
