The Effect of Different Organic Gelating Agents on Grain Size of ZnO Nanoparticles

Abstract

In this work, sol-gel method was used in order to synthesize ZnO nanoparticles. Zn(CH3COO)(2)center dot 2H(2)O was used to obtain ZnO precursor solution. To investigate the effect of organic gelating agents on grain size, various organic gelating agents such as triethanolamine (TEA), glycerin (GLY), ethylene glycol (EG), citric acid (CA) and tartaric acid (TA) were used. X-ray diffraction analysis was used for phase identification and grain size calculation. ZnO powders were characterized by using Fourier-transform infrared spectroscopy, scanning electron microscopy and atomic force microscopy.
