Synthesis of Zinc Sulfide Nanocrystals by Chemical Bath Deposition Methods

Abstract

Chemical bath deposition method was used to create zinc sulfide (ZnS) nanoparticles. The CBD contained fixed components such as ZnCl2, NH4NO3, and CS (NH2)2 and KOH. Samples were heated at 90 C in a bath with magnetic agitation. Homogeneity, high transparency, adhesion, and crystalline ZnS films were achieved using KOH (1.4 M). For structural and optical investigation, the produced nanoparticles are examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) Spectroscopy, and ultraviolet-visible (UV-Vis) Absorption Spectroscopy. In XRD, the cubic crystal structure can be seen at 350nm, the UV-Vis spectrum reveals a blue peak. The absorbance and type of bonds present in samples are determined by FTIR spectra.
