Zusammenfassung:Disclosed is an ultraviolet light-emitting device. The light-emitting device includes: an n-type contact layer including a GaN layer; a p-type contact layer including an AlGaN or AlInGaN layer; and an active region of multiple quantum well structure positioned between the n-type contact layer and the p-type contact layer. In addition, the active region of multiple quantum well structure includes a GaN or InGaN layer with a thickness less than 2nm, radiating an ultraviolet ray with a peak wavelength of 340nm to 360nm.
