摘要

采用高温固相法合成了Sr

2.95

SiO

:0.05Eu荧光粉

借助X射线衍射仪、光谱仪、激光粒度仪、扫描电子显微镜等分析测试方法分别对荧光粉的晶相、激发与发射光谱、粒度分布、表面形貌等进行了表征

进而分析了坩埚的加盖工艺对产物性能的影响。实验结果显示:随着坩埚严密程度的增加

产物在蓝光激发下的发光强度增大。坩埚加盖有利于得到Sr

SiO

相纯度高的产物。加盖后

得到的样品颗粒尺寸较大

但是粒径分布均匀。

Abstract

2.95

SiO

:0.05Eu phosphors were synthesized by high temperature solid phase method

and the phosphor phase

excitation and emission spectra

particle size distribution

surface morphology were investigated with the help of X-ray diffraction

spectrometer

granulometer and scanning electron microscopy. The influence of crucible lid-covering technology on the performance of the product was analyzed. The results indicate that the luminous intensity of the samples increases with the increasing of the crucible close degree. Crucible with lid is of benefit to the product for high purity Sr

SiO

phase. The particle size of the sample with crucible lid-covering is larger

but the size distribution is uniform.
