无机光致发光材料在受光子激发的同时,又受到光子的辐照和离子的轰击,造成材料损伤,从而引起材料的老化并产生光衰.例如,荧光灯中荧光粉由于同时受到紫外光子的辐照和汞离子的轰击,引起了荧光粉的光衰.材料的稳定性不同,粒子作用后引起材料的结构和性质的变化也不同.因此,研究材料的稳定性,对于荧光粉体系的选择和性能改善,都有一定的实际意义. 粒子对荧光粉作用主要发生在表面,因此,我们采用了表面分析光电子能谱(XPS)、辅之于顺磁共振光谱(EPR)、红外光谱(IR)等技术,对基质和激活剂进行分析,得到了如
Inorganic photoluminescence material is excited by photons, but also by photons of radiation and ion bombardment, resulting in material damage, resulting in the aging of the material and produce light failure.For example, the fluorescent phosphor in the same time by the UV photons of radiation Photo and mercury ion bombardment, causing the phosphor of the light failure. The stability of the material is different, the particles caused by changes in the structure and properties of the material are also different.Therefore, the study of material stability, the choice of phosphor system and We have used the surface analysis of photoelectron spectroscopy (XPS), supplemented by paramagnetic resonance spectroscopy (EPR), infrared spectroscopy (IR) And other technologies, the matrix and activator were analyzed, such as
