Morphologies and Microstructures of Antimony-Doped Tin Oxide Films Derived by Sol-Gel Dip-Coating Processing


Article Preview

A simple laboratory technique for the routine preparation of antimony-doped tin oxide (ATO) on float glass substrates (25×76×1mm3) was described. The process employed sol-gel dip-coating approach in the absolute ethanol solution of metal salts of tin (II) chloride dehydrate and antimony trichloride. Microstructural and morphological analyses of as-prepared films were performed at different conditions. With increase of annealing temperature from 400 to 550°C, the evolution of grain size and the morphologies of ATO films were analyzed by means of atom force microscopy (AFM). The studies on the morphological development suggested that higher annealing temperature led to a decrease in the surface roughness of the deposited films. The XRD patterns revealed that as-prepared ATO films were in the crystallization of a tetragonal rutile structure of SnO2 with highly (110) preferred orientation.
