Description
Summary:Thermochromic properties of polycrystalline molybdenum doped vanadium pentoxide thin films grown by the spray pyrolysis technique were investigated. Tetragonal thin film structures of this system are grown. The transmittance spectral analysis with temperature indicates a record semiconductor-metal transition temperature of < 50oC. This critical temperature is approximately 1/3 to 1/6 of magnitude expected for V2O5 thin films. The resistance of the thermochromic thin film also underwent a transition or phase change as expected, a reduction from more than few mega ohms to less than kilo ohm regime indicating potential applications in optoelectronics.
