铝酸锶铕系发光材料的制备及其发光机理

Preparation of photoluminescence materials of strontium europium and system aluminates and their luminescent mechanism

20世纪发现和发展起来的铝酸锶铕体系长余辉发光材料是一类重要的新型能源和节能材料.综合评述了铝酸锶铕系发光材料的光学性能,对其制备方法进行了系统描述,同时对其发光机理进行了介绍,并总结了这种发光材料的研究现状.

The long lasting phosphorescent materials composed of strontium aluminates doped with Europium, which were found in 20th century, are a kind of important energy generating and energy saving materials. The optical properties of photoluminescence materials of strontium and europium aluminates system are reviewed in this paper, the methods of preparing these material are described systematically, the luminescent mechanism, in the meanwhile, is introduced, and the current situation of investigation of this materials is summarized.
