The luminescent materials doped with rare earth have outstanding performance.So 2 crystal types of strontium titanate base materials(perovskite structure and layered perovskite structure) were synthesized by sol-gel method.And the precursor with strontium titanate base and doped with the rare earth ion Sm3+ was prepared,and calcined at high temperature to obtain the luminescent material powder with improved luminescence.The structure,morphology and performance of the prepared red phosphor were characterized in the test and the optimum doping amount of samarium was obtained.
