Nano-engineering Core/Shell Quantum Dots for Ultimate Utility in Light-emission Applications

Htoon H., Hollingsworth J.A., Los Alamos National Laboratory, US

Quantum-confinement effects have been used for decades to tune semiconductor opto-electronic properties. More recently, particle-size control as the primary means for properties control has been succeeded by nanoscale hetero-structuring. In this case, the nanosized particle [...]

Advanced Nanocomposite Materials Tailored to Solid-State Lighting Applications

Davis J.L., Guzan K., Mills K., Han L., RTI International, US

Nanofibers and nanocomposites made from nanofibers are emerging as a key enabler for the next generation of lighting technologies. The emergence of these materials in lighting applications is driven by the fact that nanofiber substrates [...]

Manipulating Optical Properties of Luminescent Nanoparticle Substrates through Inkjet Printing

Guzan K., Sumerel J., Davis L., Hoertz P., Mills K., Magnus-Aryitey D., RTI International, US

In this work, an ink jet printer has been used to deposit patterns of photoluminescent particles onto nanofiber substrates allowing control of correlated color temperature (CCT) and color rendering index (CRI) of the resultant photoluminescent [...]

Atomistic Simulations of Electronic Structure in Realistically-Sized Wurtzite InN/GaN Quantum Dots

Yalavarthi K., Gaddipati V., Ahmed S., Southern Illinois University at Carbondale, US

In this work, within a fully atomistic framework, we investigate the electronic structure of wurtzite InN quantum dots self-assembled on GaN substrates. The main objectives are two-fold: (1) to explore the origin, nature and the [...]
