چکیده
|
In this study, the chemical bath deposition (cbd) strategy was applied for preparation of pure and lithium-doped copper sulfide (cus) thin film on glass. the cucl2.2h2o, as a copper source and thiourea as a sulfur source were used. the structural, topographical, and optical properties of products were characterized via powder x-ray diffraction (xrd), atomic force microscopy (afm), and uv-vis spectroscopy. results showed that the crystalline size is increased via lithium doping, though the strain (%) parameter decrease from 30.39 to 27.47. obtained results revealed that doing of lithium has a significant effect on the optical properties of prepared cus-based thin films. the optical properties of samples was investigated through band gap calculation. the bands gap were calculated 2.4, 2.5, and 2.6 ev for cus:3% li, cus:1% li and pure cus thin films respectively. based on attractive properties of prepared thin films, lithium-doped cus thin film has potential application in optoelectronic fields.
