摘要
利用高温固相合成法在还原气氛中,合成了新型长余辉发光粉CaxSr1-xAl2O4:Eu2+,并以硼酸盐体系玻璃B2O3-(Na,K)2O-XO和硅硼酸盐体系玻璃SiO2-B2O3-(Na,K)2O-X2O-XO的低熔点玻璃作为载体,掺杂该发光粉合成了稀土蓄光发光玻璃。实验改进了合成发光玻璃的热处理方法,提出二阶段的热处理方案,确定了发光玻璃的最佳合成温度分别为820℃和880℃。并根据SEM结果,对两种发光玻璃的表面质量及发光强度进行了对比分析,发现合成的硼硅酸盐发光玻璃的稳定性和发光效果要好于硼酸盐发光玻璃。
The new-type long persistent phosphorescence powder CaxSr1-xAl2O4 ：Eu^2＋ was synthesized by the conventional solid phase reaction method in reducing atmosphere. And then two kinds of luminescent glasses were synthesized. Glass1 was prepared by doping the luminescent powder in the pure borate glass B2O3-（Na,K）2O-XO and Glass2 was grown by doping the luminescent powder in borated silicate glass SiO2-B2O3-（Na,K）2 O-X2O-XO. This experiment put forward two stages heat treatment method which improved homogenization and transparency of the luminescent glass and determined the optimal sintered temperature 820℃ and 880℃ respectively. By SEM and the contrast analysis on the surface quality and luminescent intensity of Glass1 and CJlass2, it is found that the stability and luminescent effect of Glass2 from borated silicate glass is better than that of Glass, from borate glass.
