White light-emitting diodes (LEDs) based on blue indium-gallium-nitride (InGaN) LEDs that excite yellow-green-emitting yttrium-aluminum-garnet: cerium phosphors (YAG:Ce, a nonhygroscopic, chemically inert inorganic scintillator) have a cold white emission that can be made warmer with the addition of a red-emitting component. Unfortunately, red emitters that satisfy all criteria for use in solid-state lighting (SSL) applications are [...]

George Wang, a senior investigator in solid-state lighting science, was invited to speak at the 7th Taiwan Solid-State Lighting (2013 tSSL). The conference was held on March 26th-27th in Taipei, Taiwan. The purpose of tSSL is “to bring together scientists and engineers actively engaged in research, development, and manufacturing on all aspects of Solid State [...]


ECIS-Veeco: Research Driving Down the Costs of Efficient LED Lighting

On February 14, 2013, in Energy, Energy Efficiency, Materials Science, Partnership, Research & Capabilities, Solid-State Lighting

Solid state lighting (SSL), which uses light-emitting diodes (LEDs), has the potential to be 10 times more energy efficient than traditional incandescent light bulbs. Currently, 20% of U.S. energy use powers lighting. SSL technology can potentially significantly cut U.S. lighting energy use, reducing electricity consumption for lighting by one-fourth. That’s why since 2003, the Department [...]
