U.S. Researchers Unveil Oxygen’s Role in Strengthening Red LEDs

In the fabrication of solid state lighting devices, scientists are learning, oxygen also plays a two-edged role. While oxygen can impede the effectiveness of gallium nitride (GaN), an enabling material for LEDs, small amounts of oxygen in some cases are needed to enhance the devices' optical properties. GaN doped with europium (Eu), which could provide the red color in LEDs and other displays, is one such case.

microLEDs: from headlamps to the data center When we think about the evolution of AI technology, developments in machine learning and large language models come readily to mind, as do the latest graphics processing units (GPUs), high-bandwidth... READ MORE

The question of what makes a building "smart" has been debated in the industry for years. ams OSRAM provided a clear answer at Light + Building 2026: it is light — not as illumination, but as a sensory nervous system. It percei... READ MORE
