Two-dimensional transition metal dichalcogenides (TMDCs) have attracted a lot of interest in optoelectronic applications because of their special optical and electrical characteristics. Tungsten diselenide (WSe2) is unique among them because of its powerful photoluminescence, high charge carrier mobility, and adjustable bandgap. The synthesis and characterization of WSe2 nanosheets made using a hydrothermal process are investigated in this work. Diffuse reflectance spectroscopy (DRS), and X-ray diffraction (XRD) were used to examine the optical and structural characteristics. According to the findings, the WSe2 nanosheets have a bandgap of about 1.87 eV, which qualifies them as possible options for high-efficiency solar cells and photodetectors.
