The synthesis of Ni²⁺ ion doped ZnS nanoparticles is processed via microwave assisted solvothermal method and its structure, morphology and optical properties are explored for various applications. The as synthesized samples were characterized via XRD, SEM, EDX, HRTEM, FTIR, PL and UV Visible Spectroscopy. The structural analysis of pure and Ni²⁺ ion doped ZnS nanoparticles confirms the cubic structure as well as crystalinity of the sample. The average crystallite size estimated via Scherrer equation was found to be in the range of 4−8 nm for doped and undoped ZnS nanoparticles. The doping of Ni²⁺ ion is confirmed via EDX spectra and mapping. TEM results are found to be in accordance with that of XRD report. The involvement of various functional groups are detected by FTIR spectra. The bandgap estimated via Tauc plot reveals the dependency of bandgap on the doping concentration of Ni²⁺ ion. The optical energy bandgap determined using UV–vis spectra is 3.70, 3.74, 3.77, 3.82 and 3.98 eV for pure and various concentration of Ni²⁺ ion doped ZnS.
