Preparation of tungstate and molybdate films by electrochemical method at room temperature

抄録

Highly crystallized tungstate and molybdate films (including SrWO₄, CaWO₄, BaWO₄, CaMoO₄, BaMoO₄, SrMoO₄ films) were prepared on substrates in alkaline solutions (PH=13) containing alkaline-earth ions by electrochemical method using constant direct current treatment for 50mins. in the range of (the current density is 1-1.5mA/cm²) at room temperature. The results of SEM and XRD measurement of the films show that they have single tetragonal structure of scheelite-type crystals and the average grain size of the films is 1-5μm for different kind of the films.
