碳化物的添加对长余辉发光陶瓷性能的影响

Performance Impact of Carbide’s Addition to Long Afterglow Luminescent Ceramics

采用SrAl2O4∶Eu^2+,Dy^3+的长余辉发光粉与陶瓷复合制得长余辉发光陶瓷(以下简称发光陶瓷),通过添加微量还原性碳化物、氮化物能使发光余辉时间延长,解决长余辉发光粉与陶瓷复合后余辉减短的问题。

Through blending strontium aluminate with ceramics powder to make into luminescent ceramics,and adding different content of carbide in it in order to explore the best ratio of extended afterglow duration,simultaneously,solve it’s afterglow diminish problem after it combines with other composition which made of composite materials.
