Abstract

A series of

{RE}^{3 +}

(

RE = Eu / Tb / Ce

)-activated

{Sr}_{4} La {({PO}_{4})}_{3} O

(SLPO) phosphors are synthesized with a high-temperature solid-state reaction method. The photoluminescence properties, thermal stability, morphology, and CIE values of the

SLPO : {Eu}^{3 +} / {Tb}^{3 +} / {Ce}^{3 +}

phosphors are investigated. Under 394 nm excitation, the

SLPO : {Eu}^{3 +}

exhibits red emission, and the

SLPO : {Tb}^{3 +}

presents a green emission upon 379 nm excitation, while

{Ce}^{3 +}

-doped SLPO has a broad emission band ranging from 370 to 650 nm under 337 nm excitation. The investigation results indicate that the

SLPO : {Eu}^{3 +} / {Tb}^{3 +} / {Ce}^{3 +}

phosphors can be effectively excited by near-ultraviolet light and may have the potential to serve as red-, green-, and blue-emitting phosphors for applications in white light-emitting diodes.
