Abstract

We have successfully synthesized zinc sulphide (ZnS) nanospheresdeposited on glass and silicon on insulator substrates as an acetic acid sensor. Results show that nanospheresdeposited on silicon on insulator substrate at lower ZnCl2 concentration show better response and good recovery. We found out that the sensitivity of the ZnSnanosphereswere dependent on the surface morphology and that the morphology is affected by the ZnCl2 concentrations and the substrates used. Our results show a promising potential of ZnSnanospheresas an inexpensive alternative sensing material to the existing acetic acid detectors.
