Abstract
Nickel sul des have unique and diverse structural features, making them ideal for energy conversion and storage. is research
focuses on the synthesis and characterization of nickel sul de thin lms and nanocrystals from nickel ethyl xanthate complex
using spin-coating and solventless methods. e nickel ethyl xanthate complex (C6H10S4NiO2) was characterized using Fourier transformed infrared (FT-IR), ultraviolet-visible (UV-Vis), and nuclear magnetic resonance (NMR) spectroscopies as well as thermogravimetric analysis (TGA). e NiS thin lms and nanoparticles were analyzed with energy dispersive X-ray (EDX) spectroscopy and X-ray di raction (XRD). Nickel ethyl xanthate was synthesized in an 81.2% yield. e bandgaps of the nickel sul de obtained from the spin-coating method ranged from 4.35–4.88 eV. For the solventless method, the bandgap of the nickel sul de ranged from 3.93–3.96 eV. e crystal phase observed from the spin-coating and solventless methods was α-NiS
(hexagonal). A direct correlation was observed between annealing temperature, bandgap, and particle size
