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)
Indium doped zinc oxide [ZnO:In] thin films have been deposited at 430°C on soda-lime glass substrates by the chemical spray technique, starting from zinc acetate and indium acetate. Pulverization of the solution was done by ultrasonic excitation. The variations in the electrical, structural, optical, and morphological characteristics of ZnO:In thin films,(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)
Conductive and transparent Indium-doped zinc oxide (ZnO:In) thin films were deposited on glass substrates by the ultrasonic spray pyrolysis technique. Films were prepared from 0.2 M starting solutions of zinc acetate dissolved in a mixture of water, acetic acid and methanol. Indium acetate was used as In source at three different atomic concentrations,(More)
Transparent and conductive Indium-doped zinc oxide (ZnO:In) thin films were deposited on glass substrates by the ultrasonic spray pyrolysis technique. ZnO:In thin films were prepared by mixing 0.2M zinc acetate and 0.2M indium sulphate dissolved in a mixture of water, acetic acid and methanol. Indium sulphate which acts as the In source was chosen at three(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)
