摘　　要：制备了一种新型的以透辉石为主晶相的Tb离子激活发光微晶玻璃,采用X射线衍射仪和荧光光谱仪研究了热处理温度对微晶玻璃的结构及发光性能的影响。结果表明:Tb3+掺杂SrO-MgO-SiO2微晶玻璃,其激发光谱分布在350~500nm之间,激发峰位于350 nm、375 nm、485 nm,主激发峰位于485 nm处。在485 nm波长激发下,发光颜色为绿色,发射峰位于541 nm、584 nm,主发射峰位于541 nm处。热处理温度的升高不会改变Tb3+掺杂SrO-MgO-SiO2微晶玻璃荧光光谱的峰位,随着热处理温度的升高,荧光光谱强度呈现增强的趋势。Tb3＋ doped SrO-MgO-SiO2 luminescent glass-ceramics were prepared by the melting method.The structure and luminescent properties of the glass-ceramics prepared at different temperatures were studied by X-ray diffraction.The results indicated that the excitation wavelengths of Tb3＋ doped SrO-MgO-SiO2 glass-ceramics ranged from 350 nm to 500 nm,the excitation peaks were located at 350 nm,375 nm and 485 nm while the major excitation peak was located at 485 nm.Tb3＋ doped SrO-MgO-SiO2 glass-ceramics under excitation of 485um could emit green light,showing emission peaks at 584 nm and the major emission peak at 541 nm.With the annealing temperature increasing,the position of the fluorescent spectrum peak did not change,but the fluorescence spectrum intensity did present an increasing trend.
