Films of indium selenide was deposited onto glass and indium tin oxide coated glass substrates in acidic medium using chemical bath deposition at room temperature. Indium sulphate and sodium selenosulphate were used as precursors of In3+ and Se2−, respectively. The structural, surface morphological and optical properties of the deposited films were studied. Diffractograms in structural study revealed the deposited material is In2Se3 films. Controlled bath conditions resulted in the evolution of the In2Se3 microrod-like morphology. The optical band gap of the film was found to be 1.7 eV. © 2016 Springer Science+Business Media New York

Indium sulfide films have been deposited using chemical bath deposition onto glass and indium tin oxide (ITO) coated glass substrates. The influences of different deposition parameters viz. substrate and pH have been studied. The films were characterized by different techniques with respect to their crystal structure, surface morphology and compositional property by means of X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and optical absorption. X-ray diffraction studies revealed amorphous nature of the films. The scanning electron microscopy of deposited indium sulfide film on ITO coated glass substrate shows random orientation of grains where as those on glass substrates show dumbbell shape. Optical absorption study revealed that band gap varies from 2.29 to 2.79 eV for the deposited film. © Bansode S., Kapadnis R., Wagh V., Kale S., Pathan H., 2014.

Tartrate crystals are of considerable interest, particularly for basic studies of some of their interesting properties are ferroelectric and piezoelectric compounds, exhibiting nonlinear optical and spectral characteristics. The FTIR spectrum and X-Ray diffraction for barium tartrate has been studied and structure has been solved which shows that the system of the crystal is orthorhombic of space group P212121 and 2θ ranges from 3.31 to 24.98 degree. © 2010 American Institute of Physics.

ZrO2 thick films were prepared by standard screen printing technique. Pure ZrO2 films were activated with Cr3+ by dipping them into an aqueous solution (0.1 M) of chromium trioxide CrO 3 for different interval of time 5, 10, 20, 30 minutes and fired at 550°C for 30 min. The CrO3 is known to be unstable above 197°C and transform into Cr2O3 upon firing above 197°C. The grain of Cr2O3 would disperse around the grains of ZrO2 base material. The films were characterized by XRD, SEM, EDAS, UV techniques. The gas sensing performance of different target gases was tested and the chromium activated films dipped in 10 Min. was observed to be sensitive. And highly selective 1000ppm of NH3 gas at operating temperature 300°C. The elemental composition were discussed and effect of Cr 3+ concentration on sensitivity, selectivity, response and recovery time of the sensor in the presence of different gases were studied. Reaction mechanism were discussed with better performance could attributed to an optimum number of surface misfrits in terms of Cr2O3 on the ZrO2 films. It was first time observed that crominated surface modified film have reduction in bandwidth and observed activation energy were reported. © 2012 IEEE.

In this work, thick films of pure ZrO 2 powder were prepared by screen printing technique. The material was characterized by XRD, SEM, EDAX and UV spectroscopy Techniques. X-Ray Diffraction studies confirmed that the combinations of tetragonal and monoclinic structure. The gas sensing performances of various gases were tested. The thick films showed highest response to NH 3 (100 ppm) at 300°C. The film was modified by dipping in 0.1M CdCl 2 solution for the time intervals of 5, 10, 20 and 30 minutes and surface morphology was observed by SEM technique. The sensitivity and selectivity to different gases was tested and first time it was investigated that the film showed highest response to H 2S gas at operating temperature 300°C by dipping technique. The sensitivity and selectivity may be further enhanced by Cd doping. The quick response and fast recovery time was recorded. © 2011 IEEE.

The corrosion of zinc in phosphoric acid containing Aniline has been studied at different acid concentrations, inhibitor concentration and temperatures. Corrosion increases with the concentration of acid and the temperature. At constant acid concentration, the inhibition efficiency (I.E.) of aniline increases with the concentration of inhibitor. At constant inhibitor concentration, the I.E. decreases with the increase in concentration of acid. As temperature increases, percentage of inhibition decreases. The plot of log (θ/1-θ) versus log C results in a straight line suggest that the inhibitors cover both the anodic and cathodic regions through general adsorption following Longmuir isotherm. Galvenostatic polarization curves show polarization of both anodes as well as cathodes.

Transparent conducting cadmium indium oxide films (CdIn2O4) were deposited on glass substrates at temperature of 350 and 400 °C. The film structure and surface morphologies were investigated as a function of temperature by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The XRD results showed the single phase formation of the material that revealed the presence of Cd2+ and In3+ in the inverse spinel related structure. The chemical compositional analysis of CdIn2O4 films was carried out by X-ray photoelectron spectroscopy (XPS). Room temperature photoluminescence (PL) measurements indicate that the annealed CdIn2O4 thin film exhibit blue shift effect. The optical band gap of CdIn2O4 film was increased from 3.08 to 3.2 eV up to 400 °C. ©2014 Elsevier Ltd. All rights reserved.
