A series of phosphors Ca3(1-x) (PO4)2: xRE3+ (RE=Eu, Dy, Ce, Tb) were prepared by a high temperature solid-state reaction method. Their luminescence properties were investigated. The results indicated that all samples can be effectively excited by ultraviolet light with fluerescence range from blue to red light, and they are the potential phosphors to obtain white LED excited by ultraviolet light. In the range of 0.005 ～ 0.03 mol, photoluminescence quenching concentration of Eu3+ , Dy3+ , and Ce3+ -doped are 0.025 mol, 0.025 mol and 0.02 mol, respectively, and Tb3+ -doped samples has high quenching concentration.
