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 […]

SSLS Scientist Andy Armstrong Receives 2013 Employee Recognition Award

Congratulations to SSLS EFRC Sr. Investigator Andy Armstrong, who was honored with Sandia’s 2013 Employee Recognition Award. Andy was awarded in recognition of his development and application of novel defect characterization for III-Nitride materials. Sandia’s prestigious Employee Recognition Awards (ERA) are presented to individual employees and teams nominated by their peers and chosen by a […]

Jerry Simmons Is One of Three Researchers Named as Laboratory Fellows

This status is reserved for those who are nationally or internationally recognized pioneers in their fields. It is considered a promotion to the highest level of R&D staff, equivalent to the level of management immediately below Sandia’s vice presidents. “The three new fellows have histories of sustained and equally distinguished accomplishments in their fields,” said […]

EFRC Scientist Weng Chow Awarded the Quantum Electronics Award

EFRC Sr. Investigator Weng Chow is the recipient of the 2013 Quantum Electronics Award. This highly prestigious award presented by the IEEE Photonics Society is given to a select group of scientists who are considered pioneers in the field of quantum electronics. Chow is receiving this award on behalf of his, “contributions to semiconductor-laser theory, […]

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 […]
