【摘要】：采用共烧结法制备了硼硅基质Ce:YAG荧光玻璃,研究了烧结温度在600℃~900℃范围内,Ce:YAG荧光玻璃的发光强度变化和色坐标漂移规律。结果表明,随着烧结温度的升高,Ce:YAG荧光玻璃发光强度先增强后减弱,700℃烧结时,荧光玻璃获得最大发光强度;超过850℃烧结时,荧光玻璃无发光性能;同时,色坐标(x,y)发生漂移,且比相同烧结温度的荧光粉漂移幅度大。通过X射线粉末衍射仪、差示扫描量热分析仪和X射线光电子能谱分析仪测试分析表明:随着烧结温度升高,荧光粉中的Ce~(3+)被玻璃基质氧化成Ce~(4+),玻璃液体腐蚀破坏了荧光粉YAG晶体结构,降低了荧光玻璃的发光强度,从而导致色坐标劣化漂移。
