Green synthesis and optical properties of ZnO nanoparticles.

Abstract

Human’s quest for innovation, finding solutions to problems, and upgrading the industrial yield with energy efficient and cost effective materials has opened the avenues of nanotechnology. Among various nanoparticles, Zinc oxide nanoparticles (ZnONPs) has broad applications in various areas. Green synthesis is an alternative to conventional physical and chemical methods. Green synthesis of nanoparticles is gaining importance due to its cost-effectiveness, reduction of toxic chemicals and extensive antimicrobial activity. Green synthesis of zinc oxide nanoparticles (ZnONPs) using agro waste materials particularly goat faecal matter as a reducing agent. Synthesized ZnONPs were evaluated for particle size, absorbance and photoluminescence properties using UV–visible spectroscopy. Agro-waste based green synthesized ZnONPs possess small sized particles, which enhances the good antimicrobial effect. This research will also provide a means of transforming goats wastes which would otherwise contaminate the environment into ZnONPs whose optical properties is studied for optoelectronic uses.
