ABSTRACT: High-efficiency Ultraviolet Light Emitting Diodes (UVLEDs) have attracted great attention in recent decades due to their promising applications in many fields. Such solid-state light sources are expected to replace the traditional fluorescent and incandescent lamps from the viewpoint of energy saving. Furthermore, UVLED are useful for application in the medical and biochemical fields, and the purification of the environment. In this paper, we provide an overview of research developments of UVLED. We calculate the physical and optical properties for the structure of UVLED with 3 multi-quantum wells of iAlyGa1-yN barrier - iAl0.15Ga0.85N QW - iAlyGa1-yN barrier by the SiLENSe software. This UVLED is emitted the wavelength of 330nm for sterilization.
