Paper Abstract

We present a review of our work on the development and applications of AlInGaN-based deep ultraviolet light emitting diodes (LEDs) with peak emission in the spectral range from 247 nm to 365 nm. The devices demonstrate wall-plug efficiency in excess of 2%, modulation frequency in excess of 200 MHz and very low noise performance. Single wavelength device as well as multi-wavelength high power ultraviolet lamps have been developed for applications in sterilization industry, UV-curing, optical sensors, medical, biomedical and spectroscopic instrumentation.
