CaSO4: Eu3+ phosphors prepared by co-precipitation method have been studied for its photoluminescence characteristics. The CaSO4 phosphors are prepared by doping different concentration of Europium (1,3,5 mole %). The sample shows maximum peak intensity for 5 % doping of Europium .The excitation at 254 nm and emission at 615 nm of photoluminescence was investigated.
