低温扩散Mn^(2+)制备ZnS:Mn,Cu电致发光材料

THE METHOD OF PREPARATION OF ZnS∶Mn, Cu ACEL MATERIAL BY DIFFUSION Mn2+ AT LOW TEMPERATURE

研究了不同Ｍｎ的化合物掺杂在不同退火处理条件下对ＺｎＳＭｎ，ＣｕＡＣＥＬ粉末的发光亮度的影响．在低温下扩散Ｍｎ２＋掺杂的方法，有效降低了Ｍｎ盐中其它杂质对发光的影响，和直接高温法制备的ＺｎＳＭｎ，ＣｕＡＣＥＬ材料相比，提高了材料的发光亮度．

?In this paper, the effect of different mixed compound in different annealing condition on ZnS∶Mn, Cu powder ACEL brightness was investigated. With method of Mn2+ diffusion at low temperature, the effection of other impurity in Mn compound was great weaken on luminescence. The luminescence brightness of the material diffusion Mn2+ at low temperature is higher than that of ZnS∶Mn, Cu material preparated directly at high temperature.
