摘要:
采用溶胶-凝胶法成功制备Ce3+:ZnO - Al2O3 - SiO2(ZAS)微晶玻璃。通过X射线粉末衍射（XRD）、透射电镜（TEM）和荧光光谱仪（PL）系统研究了铈离子掺杂浓度与热处理温度对ZAS微晶玻璃的结构与发光性能的影响。结果表明，900℃热处理后在非晶基体中析出了平均晶粒尺寸为13nm的ZnAl2O4尖晶石纳米晶；ZAS微晶玻璃的荧光发射峰峰值位于381nm，属于Ce3+离子的5d→4f跃迁，当Ce3+掺杂浓度为3%时发光性能达到最佳。
Abstract:
Transparent glass ceramics of Ce3+:ZnO - Al2O3 - SiO2 (ZAS) were synthesized by a sol-gel method. X-ray diffraction (XRD), transmission electron microscopy (TEM) and photoluminescence (PL) spectra were employed to study the influence of thermal treatment temperature and Ce3+ concentration on the microstructure and luminescence properties of ZAS glass ceramics. The spinel ZnAl2O3 nano-crystals sized about 13 nm distribute homogeneously among the glass matrix after thermal treatment at 900 ℃. A violet emission centered at 381 nm corresponding to the 5d→4f transition of Ce3+ ions is observed. Furthermore, the luminescence properties are the best, when Ce3+ concentration is 3%.
