| 摘 要： | 报道了一种新型的Eu~(2+)离子激活硅酸盐玻璃,该玻璃组成为2CaO-MgO-3SiO_2-0.015Eu_2O_3(CMSE)。通过透射光谱、稳态荧光光谱、余辉光谱和热释光等技术手段对CMSE的发光性质进行了深入研究。研究发现CMSE可以被紫光和近紫外光激发,获得黄色长余辉发光。热释光曲线的分析表明,CMSE的长余辉性质主要来自于玻璃基质中陷阱深度为0.83 e V左右的定域能级。研究认为对CMSE发光性质的研究有利于开发新型稀土离子激活近紫外激发LED用硅酸盐玻璃发光材料。

| Abstract: | In this article, a new Eu2+ ion activated silicate glass was prepared. The glass composition is 2CaO-MgO-3SiO2-0.015Eu2O3(CMSE). The transmitted spectrum, steady-state photoluminescence(PL) spectrum, long-lasting phosphorescence(LLP) and thermal glow were performed to investigate the luminescent properties of the CMSE sample. It was found that the CMSE sample can be excited by ultraviolet(UV) and near UV light to give yellow PL emission and LLP. The emission origins from the d-f transition of Eu2+. The results of thermal glow curve indicate that the LLP is originated from the trap level with depth of 0.83 eV in the forbidden band of glass host. This study is beneficial for finding other rare earth ions activated luminescent glasses for white light LEDs. |
