Abstract
Pure Zinc sulfide nanoparticles were synthesized by an inexpensive Solid state reaction method using zinc acetate and thiourea at different temperatures (250–450 °C). The structural, functional, optical and morphological properties were characterized by using X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, UV–Vis spectroscopy, Photoluminescence (PL) spectroscopy and Scanning electron microscopy (SEM) with Energy dispersive X-ray analysis. XRD patterns confirmed the crystalline nature and cubic structure of the prepared products. Crystallite size, microstrain and dislocation density were also evaluated from the XRD data. The functional groups present in the samples were investigated by FTIR study. A blue shift in the absorption edges was noticed in the UV–Vis spectra. The PL spectra showed three emission peaks corresponding to both UV and visible emissions. SEM revealed the abundance of spherical shaped particles and the elements Zn and S alone are identified from EDS.
