Researchers at the University of Houston have developed a prototype LED that reduces – instead of masks – the excessive blue component, while also making colors appear just as they do in natural sunlight. To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Surrey engineers’ innovative analysis of two-dimensional (2D) materials could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… A Nanyang Technological University, Singapore (NTU Singapore) team of researchers has designed a ‘smart’ device to harvest daylight and relay it to underground spaces, reducing the need to draw on traditional energy sources for lighting. In Singapore, authorities are looking at the feasibility of digging deeper underground to create new space for infrastructure, storage, […]

Kyushu University researchers have a blue light source organic light-emitting diode matching the excellent performance of the red and green ones. Using a new combination of emitter molecules, the researchers have demonstrated the promise of a novel approach to finally overcome a major challenge facing displays with high efficiency, maintaining brightness for a relatively long […]

Physicists in China, led by Yadong Wang at Hebei North University, found that higher-than-expected efficiency can be reached through interactions between triplet excitons, and impurities embedded in the LED polymer. Molecular dynamics simulations have shown that the mysteriously high efficiency of polymer LEDs arises from interactions between triplet excitons in their polymer chains, and unpaired […]
