Nanocrystalline semiconducting Cadmium Sulphide (CdS) thin films were deposited on glass substrate by relatively simple, quick and cost effective chemical bath route. The deposition kinetics played important role to get good quality nanocrystalline films with uniform thickness. By optimizing preparative parameters uniform film have been obtained. The characterization of as deposited thin films was carried out for the structural, compositional, surface morphological, and gas sensing properties using X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Gas sensing static unit. Gas sensing responses of the nanocrystalline CdS thin films were measured by exposing as deposited film to different gases like carbon dioxide (CO2), Hydrogen sulphide (H2S) and Chlorine (Cl2). It was found that the CdS thin film sensors exhibited a high sensitivity and good selectivity to Chlorine (Cl2) gas at 500 ppm and CdS thin film can be used as a new type of gas sensing material.
