Researchers demonstrate the generation of deep-ultraviolet light of wavelength ∼240 nm from AlxGa1−xN/AlN quantum wells by electron beam irradiation, with an output power of 100 mW and an efficiency of ∼40%. This record-breaking power is attributed to the high crystalline quality of the quantum wells and the proper well design for electron beam pumping.
