<p>A thin film for use as reflective film or semi-transmissive reflective film, comprising a matrix of silver or silver alloy and, dispersed therein, a phase of at least one compound selected from among gallium, palladium and copper nitrides, oxides, composite oxides, nitroxides, carbides, sulfides, chlorides, silicides, fluorides, borides, hydrides, phosphides, selenides and tellurides. The compound phase of the thin film may contain, as well as the above compounds, at least one compound selected from among silver nitride, oxide, composite oxide, nitroxide, carbide, sulfide, chloride, silicide, fluoride, boride, hydride, phosphide, selenide and telluride. This thin film reduces drop of reflectance in the long-term use, thus attaining prolongation of the life span of optical recording medium, display and other various apparatuses using the reflective film. This thin film is also useful as a semi-reflective/semi-transmissive film for use in optical recording medium.</p> |
