溶胶-凝胶法制备稀土无机发光材料及其发光性能的研究

Preparing of Rare Earth Inorganic Luminescent Material by Sol-Gel Method and Research on its Luminescent Property

报道了用溶胶 凝胶法制备可用于光转换农膜的稀土无机发光材料,用荧光分光光度计研究了其发光性能,并对实验过程中影响样品发光性能的各种因素(体系pH值、反应温度、不同稀土组合)进行了探讨,得到了优化的实验条件。当控制体系pH=9,反应温度50℃,Eu3+/Y3+值为50/50时,所得样品的发光性能较好。

The preparation of rare earth inorganic luminescent material that can be used as sunlight-transform agent on sol-gel method was introduced. The luminescent properties and influential factors(included pH value, reaction temperature, different Eu^(3+)/Y^(3+) value)of the samples were also studied. The optimum experimental conditions were obtained. At a controlled conditions of pH=9, T=50 ℃, Eu^(3+)/Y^(3+)=50/50, the highest luminescent properties of samples are obtained.
