Good News for Toshiba! Silicon-based nanoparticles could make LEDs cheaper, greener

Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones with warmer and more appealing hues.
Researchers at the Univ. of Washington have created a material they say would make LED bulbs cheaper and greener to manufacture, driving down the price. Their silicon-based nanoparticles soften the blue light emitted by LEDs, creating white light that more closely resembles sunlight.
The company, LumiSands, started as a graduate student project for CEO Chang-Ching Tu, who received his doctorate in electrical engineering at the UW and just completed a stint as a postdoctoral researcher in materials science and engineering. This spring (2013), the startup company spun out from the UW Center for Commercialization, a process that its two founders hope will lead to signing a commercialization license for the technology.
