Lights 4 Living Addresses New Alternatives for Rare Earth Elements in LEDs

Researchers at the University of Washington have created silicon-based nanoparticles to replace costly rare earth element (REE) phosphors in LEDs. Traditionally used to soften blue light, these nanoparticles, derived from sand, emit a warm red glow when smaller than five nanometers. This breakthrough allows for the enhancement of LED lighting without relying on REEs, paving the way for the development of warmer white light by adjusting to other colors like yellow and green. A representative from Lights 4 Living emphasized the significance of this innovation, highlighting its potential to make LED technology more environmentally friendly and economically viable for home use.
