A complete series of well-crystallized solid-solution oxide films, Sr1-XCaXWO4 (0≤X≤1), has been prepared on a tungsten substrate in the electrolytic solution containing Sr2+ and Ca2+ ions by an electrochemical method at room temperature (25°C). The composition of solid-solution oxide films could easily be controlled by the concentrations of Sr and Ca species in the starting solutions. The films showed only single blue emission at liquid nitrogen temperature (-196°C), strongly suggesting that they consisted of well-crystallized defect-free crystals.
