| 摘 要： | 采用水热法制备了ZnS∶Mn,Cu电致发光材料,利用透射电镜对发光材料的结构和形貌进行表征,并且探讨了Cu2+、Mn2+掺杂量和反应温度对ZnS∶Mn,Cu发光材料亮度的影响。结果显示,随着Cu2+、Mn2+掺杂量的增加,发光材料的亮度也随之增加,但对于Cu2+、Mn2+掺杂都存在最佳值,当Cu2+掺杂量0.2%,Mn2+掺杂量4%,温度150℃时,得到的电致发光材料亮度较高,粒径约10nm左右。

| Abstract: | The electroluminescent material of ZnS∶Mn,Cu was synthesized by hydrothermal method.The structure and feature of ZnS∶Mn,Cu were studied by transmission electron microscopy（TEM）,the influences of Cu2+,Mn2+ doping and temperature on luminescence intensity were discussed as well.The results show that the material with the highest brightness is obtained at 150℃ and the doping dose of Mn2+ is 4%,Cu2+ is 0.2%,and the grain size is about 10nm. |
