Ritsumeikan University published a communique, the researchers have developed a way to produce a low cost and efficient deep ultraviolet light emitting diode (LED) technology, is expected to become the deep ultraviolet light after the United Nations to limit the use of mercury is widely used.
Ultraviolet ray, in the wavelength of 200 nm to 350 nm of light, known as deep ultraviolet light, is widely used in water treatment plants, hospitals, factories, dust-free workshop air sterilization, formaldehyde treatment and other fields. In the past, a lot of deep ultraviolet light using a mercury lamp, but the United Nations Organization last year signed the "Minamata Convention" provisions to greatly restrict the use of mercury, it is necessary to develop alternative sources.
Deep ultraviolet LED can be used instead of mercury, but in the past, the use of expensive sapphire as substrate for the production of deep ultraviolet LED limits the popularity. Aoyagi Konobu et al reported senior researcher at Ritsumeikan University said, can use cheap silicone instead of sapphire as a substrate, which can significantly reduce costs.
The team believes that the new approach could substantially reduce the manufacturing costs of deep UV LED and is expected to promote large-scale production and widespread use of this deep UV light source.
