ZnS:Ag和ZnS:Cu的薄膜电致发光特性

Electroluminescence Characters of ZnS:Ag and ZnS:Cu Thin Films

:本文研究了 Zn S:Ag和 Zn S:Cu的电致发光性质。用磁控溅射镀膜机和电子束镀膜机 ,分别制备了以 Zn S:Ag和 Zn S:Cu为发光层的夹层结构薄膜电致发光器件 ,测量了电致发光光谱 ,研究了发光强度随电压、频率变化规律。结果表明 ,利用 Zn S:Ag和 Zn S:Cu均可获得蓝色电致发光。

Thin film electroluminescent devices w ith sandwich structure are fabricated using sputtering and electron evaperation s ystems.The dependencies of luminescence on the driving voltage and frequency are also measured.The results show that blue electroluminescence could be realized using ZnS:Ag and ZnS:Cu.
