An Optoelectronic Sensor Configuration Using ZnO Thick Film for Detection of Methanol

An Optoelectronic Sensor Configuration Using ZnO Thick Film for Detection of Methanol

In the present paper sensitivity of a nanocrystalline ZnO thick film to methanol vapors is reported. The sensing mechanism is the modulation in the intensity of light reflected from glass film interface. Modulation occurs due to the change in refractive index of ZnO film upon adsorption of vapor mol...
