Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have developed blue LEDs based on a material called metal halide perovskite, that, for the first time, uses asymmetrical bridges ...

Blue LEDs light the way toward sustainable development

Light-emitting diodes (LEDs) are commonly used in the electronic displays in our TVs, smartphones, and other devices; now, researchers at the Institute of Chemical Reaction Design and Discovery (ICReDD) at Hokkaido University ...
