Coating can drive down white LED light prices
http://leds-news.blogspot.com/2015/08/coating-can-drive-down-white-led-light.html
"The cost of white LED lighting may be set to fall as scientists in the US have created an LED coating made from a relatively cheap luminescent metal–organic framework (MOF). The film may supplant current white LED coatings, which consist of far more expensive rare earth elements."http://leds-news.blogspot.com/2015/08/coating-can-drive-down-white-led-light.html

"Li’s team is developing hybrid phosphor-based technologies that are much more sustainable, efficient and low-cost. They combine common, earth-abundant metals with organic luminescent molecules to produce phosphors that emit a controllable white light from LEDs. By varying the metal and organic components, the researchers can systematically tune the color of the phosphors to regions of the visible light spectrum that are most acceptable to the human eye, Hu and Li note. The team is continuing to experiment and develop other rare-earth-free LED phosphors based on different metals and organic compounds."
Splurt!
