METHOD OF PREPARING ZINC OXIDE NANORODS ON A SUBSTRATE BY CHEMICAL SPRAY PYROLYSIS

摘要

A method of preparing nanostructured zinc oxide layers on a substrate by chemical spray pyrolysis at moderate deposition temperatures from 350° C. to 600° C. is disclosed. An aqueous or aqueous alcoholic solution comprising zinc chloride or zinc acetate as precursors is prepared and sprayed onto the preheated substrate so that the precursor reacts to form zinc oxide layer on the substrate. Thiourea or urea may be also added to the solution. Glass, silicon, or metal oxide covered glass can be used as the substrate.
