Description 447-451
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.
