Abstract
The present invention provides a switchable mirror material comprising (1) a magnesium thin film having a thickness of 40 nm or less, or a magnesium-nickel alloy thin film having an alloy composition represented by MgNi (0.1<x<0.3), (2) a transparent catalyst layer formed on a surface of the magnesium-containing thin film, and (3) a transparent protective layer optionally formed on the catalyst layer. The switchable mirror material has a chromic property which allows the thin film to be switched from a mirror state into a transparent state by means of hydrogenation of the thin film at about 20° C., and to be switched from the transparent state into the mirror state by means of dehydrogenation of the thin film in the range of about 20° C. to 100° C. The present invention also provides a switchable mirror glass having a surface formed with the switchable mirror material, a switchable mirror window, a method of switching the states of a switchable mirror glass, and an article having the switchable mirror function.
