采用高温固相反应法制备了不同电荷补偿剂(Li+、Na+、K+共掺)的Sr2P2O7：Sm3+系列荧光粉和不同电荷补偿剂(Li+、Na+、K+共掺)的Sr2P2O7：Sm3+荧光粉。对制备的粉末进行了物相结构、光致发光性能和热稳定性的研究。由于Sm3+的4G5/2-6H7/2跃迁，在紫外光和蓝光照射下，Sr2-xP2O7：xSm3+荧光粉可以有效地发出橙红色的发光。发射光谱有三个发射峰，分别位于562、600和641nm处。在Sr2P2O7：Sm3+荧光粉中引入电荷补偿剂R+(R+=0.Li，Na，K)可以提高发光强度。结果表明，Sr2-xP2O7：xSm3+是一种很有前途的橙色红光荧光粉，可用于发光二极管和其他可见光器件。
A series of Sr2P2O7: Sm3+phosphors and Sr2P2O7: Sm3+doped with different charge compensator (co-doping Li+, Na+, K+) phosphors were prepared by the high temperature solid-state reaction process at 1100 °C in air. The phase structure, photoluminescence properties and thermal stability were of the as prepared powders were investigated. Sr2-xP2O7: xSm3+phosphors can be efficiently emitted an orange-red luminescence under ultraviolet and blue light irradiation due to4G5/2-6H7/2transition of Sm3+. The emission spectrum with three emission peaks is located at 562, 600 and 641 nm. The emission intensity can be enhanced by introducing the charge compensator R+(R = Li, Na, K) into Sr2P2O7: Sm3+phosphors. The results indicate that Sr2-xP2O7: xSm3+is a promising orange red-emitting phosphor that can be used in the LED's and other optical devices in the visible region.
