Development of Nano-rough Zn0.92 Fe0.08O Thin Film by High Electro-spin Technique via Solid-State Route and Verify as Methane Sensor
In this paper, development of nano-rough Zn0.92 Fe0.08O 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 °C. There are iron ions like ferrous and ferric improved to the gas sensing properties. Overall sensitivity rapidly increases with concentrations of methane at 150 °C. The deposition of NFZO by the high rpm spin pattern is low cost and simple operation.
