Synthesis Gas Sensor from CuFe2O3: Cu Films by Spin Coating
Authors: , ,
Abstract: Thin films from $$CuFe_{2}O_{3}$$: Cu were prepared with different weights and then the membranes were prepared using a spin coating method with the rotation speed are (2000,3000,4000,5000) rpm respectively and the rotation time is 7s.. The films were examined as gas sensor against NH3gas at operating temperatures (200) $$^{\circ}C$$, also sensitivity of films for gases increases with decreases temperature. The variation of the operating temperature of the films have led to a significant change in the sensitivity of the sensor. The gas sensor at the operating temperature increasing in recovery time and decreasing in response.
