文摘

Single pure M₁-phase V_1鈭?em>xZn_xO₂ thin films with various Zn concentrations were fabricated on quartz glasses by reactive magnetron sputtering. Structural, morphological and optical properties of the prepared samples were characterized. Zn doping has a great effect on the morphology of V_1鈭?em>xZn_xO₂ thin films. Particularly, the luminous transmittance of V_1鈭?em>xZn_xO₂ films largely increased and the yellow color was significantly diminished as compared with pure VO₂ films of the same thickness, which was due to the absorption-edge blueshift in the doped VO₂ thin films. This feature benefits the application of VO₂ thin films to energy efficient smart windows.
