在含有Sr2+和Ca2+离子的电解液中，用电化学方法在室温(25−°C)的钨衬底上制备了一系列结晶良好的固溶体氧化物薄膜：Sr1-xCaXWO4(0≤X≤1)。固溶氧化膜的组成可以很容易地由起始溶液中的锶和钙物种的浓度来控制。在液氮温度下(−196 °C)，薄膜只有单一的蓝光发射，这强烈地表明它们是由结晶良好的无缺陷晶体组成。
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.
