This project uses a new class of downconverter nanophosphors to more efficiently absorb UV/blue light and simultaneously downconvert to white light. The nanophosphor efficiency compares well with best commercially available YAG:Ce bulk phosphors, which are currently used to generate white light LEDs from blue LEDs.
When fully optimized, the high refractive-index nanocomposites and nanophosphors are expected to increase white light emission by 100%, bringing the luminous efficacy of white light to 75 lm/W using a cost-effective packaging technology. Combining different nanophosphors will achieve varying color temperatures.
