Mg_6As_2O_(11):Mn发光材料制备方法的改进

Improvement on the Preparation of Mg_6As_2O_11:Mn Phosphor

通过对Mg6As2 O11:Mn发光材料中激活剂Mn离子价态的研究 ,改进了Mg6As2 O11:Mn荧光粉的制备方法 ,并对所得样品的晶体结构和发射光谱进行了测试 .结果表明 ,在本实验改进条件下制备的荧光粉 ,发光强度有所提高 。

By studying the valence state of Mn in Mg 6As 2O 11 :Mn,we modified the preparation of Mg 6As 2O 11 :,Mn phosphor,measured the samples crystal structure and emission spectrum.It was found that in our experiment the samples luminescence intensity and uniform distribution had been improved.
