The present study exploits the hydrothermal method to synthesize Covellite CuS nanoparticles. To optimize the synthesized nanoparticles for their application in Blue Light Emitting Diode (BLEDs), the effect of reaction temperature on their structural and optical properties was studied at 100°C, 125 °C, and 150 °C for 12h. The diffraction and morphological studies were conducted using X-Ray Diffraction and Scanning Electron Microscopy analysis, respectively. The particle size increases with the increase in reaction temperature, and the structural parameters match well with the covellite CuS hexagonal phase prepared at 125 °C. Ultraviolet-visible absorption studies reveal that the bandgap of nanoparticles was found in the range of 2.9-3.1 eV. The Photoluminescence spectroscopy and CIE chromaticity plot show that the sample synthesized at 125 °C has a low recombination rate and emits light in the blue region, suggesting that it can be utilized in devices like BLEDs and lamps.

The present study exploits the hydrothermal method to synthesize Covellite CuS nanoparticles. To optimize the synthesized nanoparticles for their application in Blue Light Emitting Diode (BLEDs), the effect of reaction temperature on their structural and optical properties was studied at 100°C, 125 °C, and 150 °C for 12h. The diffraction and morphological studies were conducted using X-Ray Diffraction and Scanning Electron Microscopy analysis, respectively. The particle size increases with the increase in reaction temperature, and the structural parameters match well with the covellite CuS hexagonal phase prepared at 125 °C. Ultraviolet-visible absorption studies reveal that the bandgap of nanoparticles was found in the range of 2.9-3.1 eV. The Photoluminescence spectroscopy and CIE chromaticity plot show that the sample synthesized at 125 °C has a low recombination rate and emits light in the blue region, suggesting that it can be utilized in devices like BLEDs and lamps.
