摘要： 利用Na+为电荷补偿剂制备CaxSr1-x-y-zMoO4:yEu3+,zNa+红色LED荧光粉体.研究了电荷补偿剂的用量、基质材料中Ca2+的含量、合成温度、反应时间及发光中心Eu3+摩尔分数对荧光材料晶体结构和发光性能的影响.结果表明:最佳工艺条件为电荷补偿剂摩尔分数为6%,Eu3+摩尔分数为8%,Ca2+摩尔分数为60%,反应温度900℃和反应时间2 h.光谱测试结果表明,该荧光材料可被311,395或465 nm有效激发,发射峰在616 nm.

Abstract: The CaxSr1-x-y-zMoO4: yEu3+, zNa+ as a red phosphor was prepared for LED by solid-state reaction with Na+ as charge compensating agents. The effects of Na+ dose, Ca2+ content in matrix, synthesizing temperature, reaction time and the molecular fraction of Eu3+ as luminescent center on the luminescent properties and crystal structure of the phosphor were studied. The results showed that the optimum reaction conditions in molecular fraction are 6% Na+, 8% Eu3+ and 60% Ca2+ with reaction temperature 900 °C for 2 h. The luminescent spectra revealed that the red-emitting phosphor can be effectively excited at 616 nm emitting peak by 311 nm, 395 nm or 465 nm.
