Chalcogenide films find many applications in electronics as memory device, laser writer & xerography. To tailor the property to the requirement, various compositions of Cd, Te and Se have been deposited and characterized optically. Films have been deposited by thermal evaporation as well as by electron beam evaporation. Thermal analysis such as TGA, DTA and DSC has been carried out before deposition to ensure the composition. Dependence of Eg on the composition has been justified from (T% data) Transmittance measurements. Drastic changes in optical property due to annealing in the range 200°C to 400°C have been investigated. 展开更多

Ultra-fine and uniform ITO nanopowders can be prepared by very simple Combustion method. In this paper, effects of Indium oxide with Sn doping on crystallinity, band gap values by UV studies and morphological studies by SEM and TEM analysis of nanopowders are reported. Powder mixtures of In2O3:SnO2 of 90:10 compositions are prepared and calculated grain size from X-ray diffraction measurements. The free electron absorption is determined from spectral transmission and reflection measurements. Key words: In2O3:SnO2, XRD, UV, Combustion and SEM. 展开更多
