The U.S. Department of Energy (DOE) has announced the allocation of $6.4 million to support four research programs focused on solid-state lighting technologies, specifically LED and organic LED advancements. The funding, part of the Solid-State Lighting Core Technology Research program, will benefit three national laboratories and the U.S. Army Research Laboratory. Notable projects include the National Renewable Energy Laboratory’s initiative to develop green LEDs using gallium indium phosphide alloys, Sandia National Laboratories’ work to enhance green LEDs on gallium nitride substrates, the Army lab’s exploration of negative polarization charge for LED efficiency, and the Pacific Northwest National Laboratory’s effort to create stable materials for high-efficiency blue organic LEDs. These initiatives aim to address current gaps in LED technology and improve overall lighting efficiency and quality.
