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 […]
