In present study, using simple and inexpensive novel reflux method, Cadmium Oxide (CdO) thin films were successfully deposited on glass substrate. Here to deposit CdO on glass substrate, Cadmium Chloride (CdCl2) was used as a source of Cd+ ions, while ammonia was taken as complexing agent. Structural analysis and surface morphology of prepared CdO thin film was analyzed by X-ray diffraction and scanning electron microscopy respectively, Also wettability test was done by using goniometer which showed hydrophilic nature of deposited CdO thin film. Optical properties of CdO thin film was completed by using UV-Visible spectroscopy which revealed that deposited CdO thin film has direct band gap about 2.01 eV. NO2 gas sensing properties like sensitivity, response recovery & response time of prepared CdO sensor was determined by using Keithley gas sensing unit. In present work effect of concentration of NO2 gas on response of CdO sensor was studied and it was cleared that as NO2 gas concentration increases (25 ppm – 100 ppm), the response of CdO sensor was also increases & it becomes maximum i.e. (57 %) for 100 ppm of NO2 with optimized temperature of 200 C. Variation of response and recovery time with NO2 gas concentration was studied and it was concluded that as concentration of NO2 gas increases, response time increases while recovery time decreases. |
