Abstract
The silver oxide (Ag2O) nanoparticles thin films were deposited on the glass, silicon (Si), also porous silicon (PS) substrates which are kept at room temperatures using pulsed laser deposited (PLD) technique. The optical band gap related to thin films has been 2.05 eV. Also, the XRD researches specified that thin films have polycrystalline cubic phase. Prepared thin films were used in gas sensors applications. The thin film show that the sensitivity increased with increased operation temperature, the Ag2O/PS has sensitivity more than Ag2O/Si. Recovery time and response time are increased with the increase in the operating temperature which is related to Ag2O/Si, whereas the recovery time and response time are reduced with increasing in operating temperature of Ag2O/Si.
