Abstract

In this work, we report on a comprehensive study about the bridge role of Tb3+ in broadband excited Sr3Y(PO4)3:Ce3+, Tb3+, Sm3+ phosphors. With Tb3+ acting as an energy transfer bridge, Ce3+ →(Tb3+)n →Sm3+ energy transfer process was utilized to circumvent Ce3+-Sm3+ metal-metal charge transfer (MMCT) quenching in Sr3Y(PO4)3 host. Sm3+ was efficiently sensitized by the broad absorption band (4f1 →5d1 transition) of Ce3+ in near-ultraviolet spectral region. The color tones of Sr3Y(PO4)3:Ce3+, yTb3+, zSm3+ phosphors were tuned from blue through green and finally to orange with increasing Tb3+/Sm3+ doping concentration. Furthermore, energy transfer mechanisms from Ce3+ to Tb3+ (dipole-dipole mechanism) and Tb3+ to Sm3+ (exchange interaction) as well as the corresponding energy transfer efficiencies (higher than 90%) are systematically investigated. Sr3Y(PO4)3:0.02Ce3+, 0.90Tb3+, 0.02Sm3+ phosphor shows a thermal stability up to 493K, superior to that in analogous reports. The quantum efficiency of Sr3Y(PO4)3:0.02Ce3+, 0.90Tb3+, 0.02Sm3+ phosphor with 315nm excitation was calculated to be 60%.
