In-doped ZnO (IZO) thin films have been deposited onto glass substrates by the ultrasonic spray pyrolysis method. The variations of the electrical and optical properties with the indium incorporation were investigated. The optical transmittance through the films was measured in the wavelength range 300-1000 nm with the help of an UV-VIS spectrophotometer.(More)
A study on the propane gas-sensing properties of Cu-doped ZnO thin films is presented in this work. The films were deposited on glass substrates by sol-gel and dip coating methods, using zinc acetate as a zinc precursor, copper acetate and copper chloride as precursors for doping. For higher sensitivity values, two film thickness values are controlled by(More)
The physical characteristics of ultrasonically sprayed indium-doped zinc oxide (ZnO:In) thin films, with electrical resistivity as low as 3.42 × 10 −3 Ω· cm and high optical transmittance, in the visible range, of 50%–70% is presented. Zinc acetylacetonate and indium chloride were used as the organometallic zinc precursor and the doping source,(More)
