US government invests $6.4 million in LED research programs

USA - The US Department of Energy (DOE) released four research programs to propel the solid-state lighting research with a $6.4 million fund.

Named Solid-State Lighting Core Technology Research Program, it focuses on improving the efficiency and quality of solid-state white light sources. DOE said the research projects aim to plug gaps in current LED and OLED technologies.

In line with this, three US national laboraties and an Army lab will receive funds for their LED and OLED researches.

The National Renewable Energy Laboratory 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 will conduct research aimed at improving the efficiency of green LEDs grown on gallium nitride substrates.

Pacific Northwest National Laboratory will receive $1 million to develop new, stable materials for high-efficiency blue OLEDs.

Meanwhile, US Army Research Laboratory will seek to exploit the negative polarization charge to improve the efficiency of green LEDs. The Army lab also received $1.8 million in competitiveness funding.
