Calcium titanate doped with praseodymium was prepared through solid state reaction and it exhibited intense red emission at 612 nm. Phosphors were characterized for photoluminescence, thermo-luminescence and afterglow emissions. Study of effects of rare earths on photoluminescence as well as afterglow intensity was reportexi. Presence of gadolinium enhanced luminescence. Presence of some monova-lent ions enhanced both afterglow and photoluminescence emission. Thermo-luminescence glow curves were analyzed and trap parameters were estimated. Temperature dependence of luminescence was also investigated.
