Ultraviolet light emitting diodes (UV-LEDs) have rapidly evolved as a promising alternative to conventional mercury-based UV lamps in water disinfection systems. Their compact size, reduced energy ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...

Researchers successfully conducted a room-temperature continuous-wave lasing of a deep-ultraviolet laser diode (wavelengths down to the UV-C region). A research group led by 2014 Nobel laureate ...

Development led by 2014 Nobel laureate Hiroshi Amano at Institute of Materials & Systems for Sustainability. Nagoya group achieved room-temperature CW lasing of a deep-UV laser diode. A research group ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

Ultraviolet-B (UV-B) semiconductor lasers are required for medical, biotechnology, and precision manufacturing applications; however, for a long time UV-B laser diodes have been limited to pulsed ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...

LED lighting technology is increasingly adopted for its energy efficiency, durability, and longevity, making it an ideal solution for modernizing urban areas and developing smart city infrastructures.

A research group led by 2014 Nobel laureate Hiroshi Amano at Nagoya University's Institute of Materials and Systems for Sustainability (IMaSS) in central Japan, in collaboration with Asahi Kasei ...
