| Abstract: | Highly crystallized luminescent SrWO4 film has been prepared on a tungsten substrate in an alkaline solution containing strontlum ions by an electrochemical method using constant direct current of 1 mA/cm2 at room temperature (25°C). This film showed only a single blue emission at 461 nm with the excitation of 248 nm at liquid nitrogen temperature (- 196°C), strongly suggesting it consists of well-crystallized defect-free crystals. |
