| 摘 要： | 采用掺杂2种激活剂制备了粉末电致发光材料ZnS:Cu,Au,发现激活剂Cu+,Au+的掺杂量对材料亮度有较大影响.当掺入激活剂Au+与基质ZnS的质量比为0.05%,而掺入Cu+的量比达到0.29%时,得到了在400 Hz,150 V激发下,亮度可达105 cd/m2的绿色电致发光材料.通过光谱分析发现,掺杂后并没有改变发光材料的颜色.同时,用扫描电子显微镜(SEM)对ZnS:Cu,Au颗粒进行了尺寸和形貌表征. |

| Abstract: | Electroluminescence powder ZnS :Cu,Au was prepared by doping two activators:Cu,Au.It was found that the concentration of activators Cu ,Au greatly influent the luminance of the material.When the concentration of Au ,Cu were 0.05% and 0.29%,respectively,the green luminous material was obtained under the condition of 400 Hz,150 V and its brightness was 105 cd/m2.The spectrum showed that the doped activator didn't change the color of the luminous material.Meanwhile,the morphology of ZnS:Cu,Au was analyzed by SEM. |
| Keywords: | electroluminescence dope ZnS activator |
