Study on gallium oxide-based deep ultraviolet light emitters

We aimed at developing new semiconductor-based LEDs, which may lead to brighter and cheaper LED bulbs. The results suggested the requirement of further efforts from the more basic points of views, but the evolution is positively expected. On the other hand, this semiconductor was found to be promising for new devices supporting our secure and safe life, for example, those monitoring ultrasonic sanitization processes for water or foods and those detecting fire at the earliest stage with flame monitoring.
