Structural, optical and electrical properties of indium tin oxide thin films prepared by spray pyrolysis
Abstract Spray pyrolysis process has been used to deposit highly transparent and conducting films of tin-doped indium oxide onto glass substrates. The electrical, structural and optical properties have been investigated as a function of various deposition parameters namely dopant concentrations, temperature and nature of substrate. The morphology of the surface as a function of the substrate temperature has been studied using atomic force microscopy. XRD has shown that deposited films are polycrystalline without second phases and have a preferred orientation (4 0 0). Indium tin oxide layers with low resistivity values around 4×10 −5 Ω cm and transmission coefficients in the visible and near-infrared range of about 85–90% have been easily obtained.
Preliminary investigations were undertaken to evaluate infrared thermography as a potential tool to assess the thermal characteristics of pigs and specifically the effects, duration and extent of skin wetness. In this study, the specific aims were to evaluate the impact of (1) timing, (2) camera angle and (3) impact of diameter curve on the resulting IT images of pigs. Based on the preliminary results, a number of recommendations were made to maximise the success of taking thermal images of live pigs.
