TL;DR: In this paper, the desired properties of phase pure CuO with good crystal quality and conductivity have been optimized with respect to pyrolytic temperature, and the results revealed good response even at room temperature, with characteristics dependent on the size of the grains and the concentration of ethanol.
Abstract: In the present work, copper oxide thin films have been deposited at different substrate temperatures from 250 to 400 °C by spray pyrolysis technique. The desired properties of phase pure CuO with good crystal quality and conductivity have been optimized with respect to pyrolytic temperature. X-ray diffraction studies and Hall effect measurements indicated that these two properties are achieved at an optimum temperature of 350 °C. The band gap of CuO films was found to decrease from 1.8 to 1.2 eV with increase in substrate temperature, based on the UV-absorption spectrum of the film. The microstructures revealed that the film optimized at 350 °C, showed uniform surface with trapezium shaped particles, which are well compacted. The dynamic sensing behavior of the optimized p-type CuO sensor, prepared at a substrate temperature of 350 °C, was used to sense ethanol for concentrations: 100 and 200 ppm. The response time and the recovery time were within the range of 15–20 s and 15–18 s, respectively. The results revealed good response even at room temperature, with characteristics dependent on the size of the grains and the concentration of ethanol.
