Abstract

The effects of pure ZnO and copper (Cu) dopant on the properties of ZnO thin films grown by chemical bath deposition (CBD) and dip coating method on glass substrates are investigated. For more comparison purpose, powder samples of pure ZnO and Cu-doped ZnO prepared at room temperature. Optical properties are investigated through UV–vis–NIR transmission spectroscopy. Raman spectroscopy from ZnO films has been investigated. Photoluminescence spectra of the samples shows prominent peaks corresponding to blue emission and defect-related green emission in the visible region at room temperature and their possible mechanism have also been discussed.

胶体溶液法合成未掺杂和掺杂Cu的ZnO薄膜的合成，光学和光致发光性能

摘要

研究了纯ZnO和铜（Cu）掺杂剂对通过化学浴沉积（CBD）和浸涂法在玻璃基板上生长的ZnO薄膜的性能的影响。为了进行更多比较，在室温下制备了纯ZnO和Cu掺杂的ZnO的粉末样品。通过紫外可见近红外透射光谱研究光学性质。ZnO薄膜的拉曼光谱已被研究。样品的光致发光光谱在室温下在可见光区域显示出与蓝色发射和缺陷相关的绿色发射相对应的突出峰，并对其可能的机理进行了讨论。
