Transparent conducting Cr doped indium oxide thin films (In 2O3: Cr) were deposited on glass substrates by flash evaporation method and the influence of Cr doping concentrations on the structural and optical properties of the films had been investigated. The as deposited films exhibited amorphous in nature, after which it changed to cubic crystalline when the films annealed at 250°C for 2 hrs. The annealed films, exhibited an average optical transmittance of 50% in the IR region with a band gap of 2.9 eV. © 2012 American Institute of Physics.
