The first directly emissive colour displays were developed in the 1960s and relied on red gallium arsenide (GaAs) and green gallium phosphide (GaP) light-emitting diodes (LEDs) 1. Subsequently, yellow ...
The III-nitride light-emitting diodes (III-N LEDs) coated with phosphors are currently the most efficient white light sources for general lighting 1,2,3,4. The most efficient violet III-N LEDs reach ...
Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...
