LEC observation shows they change their electronic state over time during field emission. OMU scientists found the result by measuring their optical absorption via lamp light […]

University of Michigan researchers have developed a new electrode that could free up 20% more light from organic light-emitting diodes. It could help extend the battery life of smartphones and laptops, or make next-gen televisions and displays much more energy efficient.   The approach prevents light from being trapped in the light-emitting part of an […]

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, […]

Kobe University’s Associate Professor Tachikawa Takashi and Dr. Karimata Izuru have succeeded in completely substituting the halide ions of perovskite nanocrystals (see #1 below) while maintaining their morphology and light-emitting efficiency. Hybrid organic-inorganic perovskites (see #2 below) have received much attention as potential next generation solar cells and as materials for light-emitting devices. By using […]
