WASHINGTON The Energy Department will fund LED and organic LED research with funds from the economic stimulus package approved by Congress in February.
The Energy Department said Monday (Aug. 24) that four research programs will be funded under a $6.4 million program to fund solid-state lighting research. Three national laboraties and an Army lab will receive funds under the program.
The Energy Department previously sought research proposals under its Solid-State Lighting Core Technology Research program. "These selections focus on improving the efficiency and quality of solid-state white light sources," DoE said in a statement announcing the awards.
Research funding will be divided as follows:
The National Renewable Energy Laboratory (Golden, Colo.) will receive $1.8 million to demonstrate the viability of high bandgap gallium indium phosphide alloys for use in making green LEDs.
Sandia National Laboriatories (Albuquerque, N.M.) will conduct research aimed at improving the efficiency of green LEDs grown on gallium nitride substrates.
U.S. Army Research Laboratory (Adelphi, Md.) will seek to exploit the negative polarization charge to improve the efficiency of green LEDs. The Army lab also received $1.8 million in stimulus funding.
Pacific Northwest National Laboratory (Richland, Wash.) will receive $1 million to develop new, stable materials for high-efficiency blue organic LEDs.
DoE said the research projects aim to plug gaps in current LED and organic LED technologies.
