Synthesis and photoluminescence properties of Sr4La(PO4)3O:RE3+(RE=Eu/Tb/Ce) pho

A series of RE3+ (RE=Eu/Tb/Ce)-activated Sr4La(PO4)3O (SLPO) phosphors are synthesized with a high-temperature solid-state reaction method. The photoluminescence properties, thermal stability, morphology, and CIE values of the SLPO:Eu3+/Tb3+/Ce3+ phosphors are investigated. Under 394 nm excitation,
