Abstract
Investigation of ZnO nanorods by photoluminescence technique for optimization characteristics of sensitive element SAW of CO sensor
Sensitive element of CO sensor was created by pulsed laser deposition and it was integrated in device of surface acoustic waves (SAW). Photoluminescence was used to control of oxygen-related defects of ZnO nanorod arrays. It is shown that the deficiency of oxygen in zinc oxide nanorods can be increased by change in temperature synthesis of nanorods of 850 to 915 ° C with a high argon pressure, and control of the deficiency of oxygen by increasing the ratio of the intensity of radiation in the visible region of the luminescence intensity in the ultraviolet region of the spectrum can help to increase the sensitivity of CO.
