Year: 2025
Type: article
Abstract: Copper sulphide (Cu2S) is an indirect gap p-type semiconductor belonging to I-VI group. The wet chemical route was used to synthesize manganese (Mn) doped copper sulphide nanoparticles with a decrease in particle size by increasing the concentration of manganese element. These nanoparticles were analyzed by using the various characterization techniques like ultraviolet-visible (UV) absorption spectroscopy, photoluminescence (PL) spectroscopy and transmission electron microscopy (TEM). The dip coating method was used to prepare Mn doped Cu2S thin films on fluorine doped tin oxide (FTO) glass slides with varying the dip time. These thin films were heat treated in air atmosphere at 420°C for 20 minutes and investigated by using the various analysis techniques like scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive analysis by X-rays (EDAX) and mapping. The detailed explanation of obtained experimental results is discussed in this paper.
