Effect of precursor type on Optical, grain sizes and Structural Properties of Zinc Oxide Nanoparticles using Cassia leaf extract as capping and Reducing agent
Authors: , ,
Abstract: Because of its special qualities and uses in optoelectronic devices, zinc oxide nanoparticles
have drawn the attention of researchers in recent years. At ambient temperature, zinc oxide
nanoparticles have a very significant excitation binding energy of 60 meV and band gap energy of 3.37
eV. It is also environmentally benign, non-toxic, and transparent to the visible spectrum. Zinc acetate,
zinc chloride, and zinc sulphate precursors were used in the current study to create zinc oxide
nanoparticles utilizing a green technique. Cassia leaf extract was used as a precursor and capping agent.
Distilled (DW) water was utilized as the solvent, and 1M sodium hydroxide was added in drops to get
the pH to 11.6. The produced zinc oxide nanoparticles' morphology and structure were examined by the
use of X-ray diffraction (XRD), spectroscopy, and scanning electron microscopy.
