▎ 摘　　要

This work focus on a modified chemical bath deposition of Cu+-and Zr4+-doped CuS/reduced graphene oxide (rGO) hybrid films. The deposition was performed in the condition of controlling S/Cu molar ratio and appropriate doping in precursor solution. Raman analysis indicated that introduced graphene oxide was well reduced. The Cu+-and Zr4+-doped CuS/rGO films showed p-and n-type electrical conduction. The hybrid films also showed low electrical resistivity. The conductivity was increased by the Cu+-and Zr(4+)doping and further increased by the rGO introduction. Moreover, the optical bandgaps, extinction coefficient, refractive index, dielectric constant, and optical conductivity of the films were calculated from the transmittance and reflectance spectra. The variation in the optical properties due to the Cu+ and Zr4+ doping and rGO introduction were observed. The increase in photoconductivity and the decrease in photoluminescence intensity due to rGO confirmed the formation of highly efficient heterojunction at the interface between CuS and rGO.
