SrAl_2O_4∶Eu的荧光效应及其陶瓷漫反射特性

Fluorescence Effect of SrAl_2O_4∶Eu and Diffuse Reflectivity of SrAl_2O_4∶Eu Based Ceramics

采用SrAl2 O4∶Eu荧光材料为主相制备具有紫外线转换功能的陶瓷泵浦腔材料。研究了SrAl2 O4∶Eu粉体制备与荧光性能的关系 ,考察其与低折射率玻璃复合制成陶瓷的漫反射性能及反射谱特性。结果显示SrAl2 O4∶Eu基陶瓷作为泵浦腔用材料在技术上是可行的。

SrAl 2O 4∶Eu was adopted as main phase to prepare the ceramic pumping cavity material with ultraviolet(UV) converting function in order to match with laser absorption spectra. The relationship between SrAl 2O 4∶Eu powder processing and fluorescence effect was studied. The glass material with lower refractive index was added into the SrAl 2O 4∶Eu based ceramics. The diffuse reflectivity and the influence of fluorescence effect on reflection spectra of the ceramics were investigated. Some experimental results for evaluating technical feasibility of the SrAl 2O 4∶Eu based ceramics used for laser reflectors were given.
