Title

Influence of Sn dopants on the response of zinc oxide (ZnO) thin films to acetone vapour

Abstract

Abstract: A spray pyrolysis technique have been used to fabricate Sn-doped zinc oxide (ZnO:Sn) thin films using Zn (CH3COO)2 as a precursor solution and SnCl4 as the doping solution. The concentration of doping is varied from 0 to 1.5 at%. The structural, morphological, optical and electrical properties of the films are explored and then tested for acetone sensing. Structural studies show that the films are polycrystalline in nature, possessing “hexagonal wurtzite” structure. The optical energy gap is found to be increasing with an increase in Sn doping concentration. The resistivity of the films decreases with dopant concentration up to 0.5at%, while at a higher doping concentration of 1at%, the disorder produce in the lattice causes an increase in the resistivity of the film. It is observed that compared to undoped ZnO film, ZnO:Sn films show higher response to acetone. Among all the doped films studied, the 0.5 at% Sn doped ZnO film show the highest response (92.03%) to 500 ppm of acetone in air at 3000C. Further the films show faster response and recovery at higher operating temperatures.
