Mg doping of thermochromic VO{sub 2} films enhances the optical transmittance and decreases the metal-insulator transition temperature

Thermochromic films of Mg{sub x}V{sub 1-x}O{sub 2} were made by reactive dc magnetron sputtering onto heated glass. The metal-insulator transition temperature decreased by {approx}3 K/at. %Mg, while the optical transmittance increased concomitantly. Specifically, the transmittance of visible light and of solar radiation was enhanced by {approx}10% when the Mg content was {approx}7 at. %. Our results point at the usefulness of these films for energy efficient fenestration.
