摘要: 利用水热法合成了NaY(WO4)2:Dy3+上转换荧光粉. 通过XRD、SEM表征该荧光粉结构和形貌. 探讨了Dy3+浓度、pH值、反应温度及焙烧温度对NaY(WO4)2:Dy3+晶体结构、形貌及发光性能的影响,得到在Dy3+浓度为0.5%,pH=8,反应温度180℃,800℃焙烧条件下的样品具有最佳上转换发光性能. 利用776 nm近红外光激发NaY(WO4)2:Dy3+,观察到480 nm处的蓝光发射峰以及577 nm处的黄光发射峰. 其中蓝光来自Dy3+离子的4F9/2→6H15/2跃迁,黄光由Dy3+离子4F9/2→6H13/2跃迁产生.

Abstract: Single Dy3+ doped NaY(WO4)2 up-conversion luminescence phosphor was prepared by hydrothermal method, and its properties were characterized by XRD and SEM. The effects of doping concentration of Dy3+, pH value, reaction temperature and roasting temperature on its structure, morphology and luminescence properties were investigated. The optimum synthesis conditions of NaY(WO4)2 with the best luminescent properties were obtained as the concentration of Dy3+ at 0.5%, pH=8, reaction temperature 180℃ and roasting temperature 800℃. Under 776 nm excitation of NaY(WO4)2:Dy3+, the blue emission peak at 480 nm and yellow one at 577 nm were observed. The blue emitting light resulted from the transition of 4F9/2→6H15/2 of Dy3+, and yellow one from the transition of 4F9/2→6H13/2 of Dy3+.

Key words: up-conversion, NaY(WO4)2:Dy3+, hydrothermal method, phosphor
