Abstract
Zinc sulphide (ZnS) nanoparticles have been synthesized by the mechanochemical route. The prepared nanoparticles have been analyzed by X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM), Energy-dispersive analysis of X-rays (EDAX), Ultraviolet-visible-near infrared (UV-Vis-NIR) spectrophotometer and photoluminescences (PLs) spectrophotometer. The crystallite size of as prepared nanoparticles are found to be in the 4-7 nm range. EDAX spectrum confirmed the composition of ZnS sample. The value of optical band gap has been found to be in the range 4.04-4.6 eV. Room temperature photoluminescence (PL) spectrum of the samples exhibits a blue light emission under UV excitation wavelength of 280 nm. Thermal analysis studied with the help of Differential thermal analysis (DTA), Differential thermogravimetric (DTG) and thermogravimetric analysis (TGA).
