| Abstract: | With the continuous development of groupⅢnitride semiconductor technology,AlGaN-based ultraviolet(UV)LEDs have received great attention.This paper mainly introduces research progress of UV-LEDs in recent years.Currently,performance of the device is restricted due to a list of technical problems,such as epitaxy,doping efficiency and light extraction efficiency.It is believed that with continuous development and research effort,UV LED performance will be greatly improved and its application scenarios will include but not limited in disinfection and purification,environmental monitoring,curing,light therapy,communications etc. |
