Nanostructured ZnO Thin Films For Sensor Applications

Nanostructured ZnO thin films were deposited onto glass substrates using ultrasonic spray pyrolysis (USP) technique. Zinc acetate was used as a starting precursor. These films were fired at 500oC. As prepared thin films were studied using XRD, AFM, TEM and EDAX to know crystal structure, size of crystallites, surface morphology, microtopography and elemental composition respectively. The absorption and photoluminescence spectroscopy was study the optical properties of the films. The crystallite size and surface roughness were observed to be increased with increase in film thickness. The band gap was observed to be decreased with increase in film thickness. The gas sensing performance of the nanostructured ZnO thin films, sprayed for different intervals of time, was studied on exposure of various conventional gases. The films were observed to be most sensitive to Liquid Petroleum Gas at 300oC. The photoconductivity was studied under different light intensity. It decreases with increase in film thickness. 

Keywords: Ultrasonic spraying, thin films, sensor, nanostructured ZnO, LPG sensing, fast response, quick recovery, photoluminescence, photoconductivity.
