2013 SPIE Intweviews George Wang: Developing next-generation lighting using nanowires January 14, 2013 George Wang, a senior investigator in the SSLS, was interviewed about his work in the EFRC on nanowire growth and the possibility of achieving ultra-efficient solid-state lighting. You may view his interview at: http://spie.org/x91938.xml 2012 Red-Emitting Quantum Dotes for Solid-State Lighting December 3, 2012 [...]
Light Creation Materials Different families of inorganic semiconductor materials can contribute to solid-state white lighting. The primary chemical systems used for LEDs are Group-III nitrides and Group-III phosphides. It is, however, possible that breakthroughs in a different material system, for example ZnO, will be important. AlGaInN Materials LEDs based on gallium nitride (GaN) and ternary [...]
Wavelength Conversion Materials Rare-Earth Phosphors Inorganic phosphors doped with rare-earth metals are used for a variety of applications. A wide array of these phosphors has been developed for use with fluorescent lamps. The first SSL white LEDs have used an yttrium aluminum garnet doped with trivalent cerium (YAG:Ce+3) to convert output from a blue LED [...]
White Light Creation Architectures The entire spectral range of visible light can be produced by III-V semiconductor LEDs. AlGaInP LEDs can cover the spectral range from red to amber, and their commercial production is relatively mature. AlGaInN LEDs are the prime candidates for producing wavelengths from blue to yellow. Two main approaches for producing white [...]
