Synthesis and characterisation of ZnO nanoparticles embedded in glucose and PVA matrix

Gunjan Patwari, Ranjit Singha

Abstract :

<p>Zinc oxide (ZnO) nanoparticles have been synthesised through chemical bath deposition(CBD) method using glucose and poly vinyl alcohol (PVA) respectively as capping agent. The XRD, HRTEM and UV–Visible characterisation techniques were employed. Tauc’s plot of PVA capped sample yield direct band gap of 5.72eV. Blue shifting observed in the absorption edge of the UV–Visible spectra confirms quantum confinement. Good crystallinity has been inferred from XRD spectra. In the XRD spectra of PVA capped sample of 0.5M molarity of nano ZnO synthesised at a temperature of 800 C. Crystallite size calculated using Scherrer formula was found to be of 2.08nm. HRTEM images show nanocrystals and quantum dots of ZnO.</p>
