This investigation focused on synthesizing nanoclusters comprising single-phase nickel sulfide via a one-step hydrothermal method. This study confirmed the presence of single-phase nickel sulfide by using X-ray diffraction (XRD) to investigate the material’s phases using sophisticated characterization techniques. Ni3S4’s optical properties were investigated using UV spectroscopy. With a tunable band gap of 1.5 eV, the synthesized material shows absorption in both the visible and UV spectra. Furthermore, our investigation of surface morphology, as seen in field emission scanning electron microscopy (FESEM) pictures, exposed irregular polyhedral-shaped nanoclusters, providing insight into the single-phase nickel sulfide nanocomposites’ fascinating structural characteristics. These characterizations highlight the potential of such materials in photovoltaic applications to enhance performance and efficiency.

摘要

This investigation focused on synthesizing nanoclusters comprising single-phase nickel sulfide via a one-step hydrothermal method. This study confirmed the presence of single-phase nickel sulfide by using X-ray diffraction (XRD) to investigate the material’s phases using sophisticated characterization techniques. Ni3S4’s optical properties were investigated using UV spectroscopy. With a tunable band gap of 1.5 eV, the synthesized material shows absorption in both the visible and UV spectra. Furthermore, our investigation of surface morphology, as seen in field emission scanning electron microscopy (FESEM) pictures, exposed irregular polyhedral-shaped nanoclusters, providing insight into the single-phase nickel sulfide nanocomposites’ fascinating structural characteristics. These characterizations highlight the potential of such materials in photovoltaic applications to enhance performance and efficiency.
