Abstract By alloying GaN with AlN the emission of AlGaN light-emitting diodes can be tuned
to cover almost the entire ultraviolet spectral range (210–400 nm), making ultraviolet light …

AlGaN-based materials own direct transition energy bands and wide bandgap and thus can
be used in high-efficiency ultraviolet (UV) emitters and detectors. Over the past two decades …

In this paper, recent advances in AlGaN-based deep-ultraviolet (DUV) light-emitting diodes
(LEDs) are demonstrated. 220–350-nm-band DUV LEDs have been realized by develo** …

The COVID-19 pandemic has generated great interest in ultraviolet (UV) disinfection,
particularly for air disinfection. Although UV disinfection was discovered close to 90 years …

Ultraviolet light-emitting diodes (UV-LEDs) have started replacing UV lamps. The power per
LED of high-power LED products has reached 12 W (14 A), which is 100 times the values …

Abstract Deep‐ultraviolet (DUV) solar‐blind communication (SBC) shows distinct
advantages of non‐line‐of‐sight propagation and background noise negligibility over …
