13 mW operation of a 295–310 nm AlGaN UV-B LED with a p-AlGaN transparent contact layer for real world applications

Abstract

Smart, high-power ultraviolet (UV)-B light-emitting diodes (LEDs) are demanded for real world applications, including vitamin D3 production in human skin (295–304 nm), immunotherapy (310 nm) and enriching phytochemicals in plants (310 nm).
