HIGHLY CONDUCTING AND TRANSPARENT SPRAYED INDIUM TIN OXIDE

Spray pyrolysis process has been used to deposit highly transparent an d conducting films of tin doped indium oxide onto glass substrates. Th e electrical, optical and structural properties have been investigated as a function of various deposition parameters namely dopant concentr ations, temperature and nature of, substrates. X-ray diffraction patte rns have shown that deposited films are polycrystalline without second phases and have preferred orientation [400]. Indium tin oxide layers with small; resistivity value around 7.10(-5) Omega.cm and transmissio n coefficient in the visible and near IR range of about 85-90 % have b een easily obtained.
