以稀土、钒的氯化物为原料, 以氨水、双氧水和磷酸氢二铵溶液作复合沉淀剂, 采用共沉淀工艺合成了YP1-xVxO4∶RE3+ (RE=Sm, Eu, Dy, Tm, Er)荧光粉. 利用XRD, SEM, 紫外以及真空紫外激发下的发射光谱对其进行表征, 并探讨其实际应用的可能性. 结果表明, 共沉淀法合成的稀土钒磷酸盐荧光粉颗粒形貌规则、均一; YP0.2V0.8O4∶Eu3+荧光粉发射主峰位于619.5 nm, 是现有PDP商品(Y, Gd)BO3∶Eu3+荧光粉的良好替代品; 发射橙红光的YP0.4V0.6O4∶Sm3+荧光粉是价格低廉的稀土三基色灯用Y2O3∶Eu3+红粉的替代品; Dy3+, Tm3+共掺杂YP0.4V0.6O4可直接得到发白光的二基色灯用荧光粉.
