A research team led by the School of Engineering of The Hong Kong University of Science and Technology (HKUST) has made significant advances in quantum rod light-emitting diodes (QR-LEDs), setting record-high efficiency level for red QR-LEDs. This innovation is poised to revolutionize next-generation display and lighting technologies, offering smartphone and television users a vibrant and enhanced visual experience. LEDs have been widely used in electronic products for decades. Recent developments in quantum materials have given rise to quantum dot LEDs ...

Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world’s brightest and most energy efficient quantum rod LEDs (QRLEDs). These next-generation QRLEDs feature optimized deep green emission at the top of the color triangle, enabling displays with unprecedented color purity and a maximized color gamut. Boasting a longer lifespan and triple the brightness of previous models, these cutting-edge light sources deliver energy-efficient, ultra-vivid ...

It is reported that Hong Kong University of Science and Technology (HKUST) has developed silicon substrate green and yellow nitride semiconductor LEDs. Details of the development were published in the May 29th issue of IEEE Electronic Device Letters. The researchers claim their 565nm yellow LEDs are the first multi-quantum well (MQW) devices produced on silicon. The researchers used metal-organic chemical vapor deposition (MOCVD) to grow the initial template, grown on 2-inch silicon. The template consisted of aluminium nitride (AlN) nucleation, 8 pai...
