Sandian Receives the Illuminating Engineering Society of North America, South Region Technical Award

The Illuminating Engineering Society (IES) builds on a century of excellence to create the premier lighting community dedicated to promoting the art and science of quality lighting to its members, allied professional organizations, and the public. This Regional Award is given in recognition of meritorious technical achieve­ment that has furthered the profession, art, or knowledge […]

Novel Nanoparticle Production Method Could Lead to Better Lights, Lenses, Solar Cells

Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants (protective coverings or coatings) for light-emitting di­odes (LEDs), solar cells and other optical devices. Industry has shunned TiO2 nanoparticles because they have been difficult and expensive to make, and current methods produce particles that are too […]

Sandia Develops a Synthesis of Quantum Dots that Increases the Quantum Yield to 95.5%

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 […]

ECIS-Veeco: Research Driving Down the Costs of Efficient LED 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 […]
