【Abstract】 Compared with traditional mercury lamps, ultraviolet light-emitting diodes(UV LEDs) have the advantages of environmental protection, controllable wavelength and so on. And UV LED has broad application prospects in sterilization, light curing, laser printing, medical and other fields. Although the performance of semiconductor-based UV light-emitting diodes has made significant progress in recent years, there are still many technical bottlenecks to be resolved. Through the detailed analysis of the problems encountered in the development of UV LED, its development direction is prospected in the paper.更多还原
