摘　　要：采用了X射线衍射、透射电镜和吸收光谱及荧光光谱技术研究了K2 O ZnO Al2 O3 B2 O3 SiO2 系掺Cr3 +玻璃的析晶性能和光谱。研究结果表明 :在K2 O Al2 O3 B2 O3 SiO2 系掺Cr3 +玻璃的基础上引入ZnO后 ,析晶性能明显改善 ;析晶温度降低 ,析出的纳米莫来石微晶均匀、规则 ;The crystallization and optical spectra of the Cr 3+ doped K 2O-ZnO-Al 2O 3-B 2O 3-SiO 2 glasses were studied by X\|ray diffraction (XRD), transmission electron microscopy (TEM), absorption spectra and fluorescence spectra. The experimental results show that the addition of ZnO to the Cr 3+ doped K 2O-Al 2O 3-B 2O 3-SiO 2 glass makes the crystallizability of glass improve obviously, the crystalline temperature decrease and the nanometre grade mullite micro-crystal more uniform and regular. As a result the luminescence of glass-ceramics is stronger.
