Development of Nano-rough Zn_(0.92) Fe_(0.08) O Thin Film by High Electro-spin Technique via Solid-State Route and Verify as Methane Sensor

摘要

In this paper, development of nano-rough Zn_(0.92) Fe_(0.08) O thin film (NFZO) on glass substrate and application in the detection of methane are reported. The deposition of film used technique is high electro-spin 500-3500 rpm pattern. Doping of 8% iron in zinc oxide synthesized by solid-state route and chemical route is applied in spin coating. Study of thin film characterizions by HR-SEM, EDX and AFM, while sensor response for 100-300 ppm methane at 150 ℃. There are iron ions like ferrous and ferric improved to the gas sensing properties. Overall sensitivity rapidly increases with concentrations of methane at 150 ℃. The deposition of NFZO by the high rpm spin pattern is low cost and simple operation.
