Abstract
A III-nitride LED with simultaneous visible and ultraviolet (UV) emission, in which the visible emission is due to conventional InGaN active region mechanisms and the UV emission occurs due to Auger carrier injection into a UV light emitting region, such as impurity-doped AlGaN. The primary application for the III-nitride LED is general airborne pathogen inactivation to prevent the transmission of airborne-mediated pathogens while being safe for humans.
