Preparation of crystallized Sr_1-xCa_xMoO₄ solid-solution films by an electrochemical method at room temperature and their luminescence

A complete series of well-crystallized solid-solution Sr_1-x-Ca_x-MoO₄ films has been prepared on molybdenum substrates in an electrolytic solution containing Sr²⁺ and Ca²⁺ ions by an electrochemical method at room temperature (25°C). The peak positions of excitation and emission of the Sr_1-xCa_xMoO₄ solid-solution films were independent of the Ca content: 285 ± 2 nm for excitation and 536 ± 2 nm for emission at liquid-nitrogen temperature (-196°C).
