Quantum dots for displays and lighting

Seth Coe-Sullivan

Year: 2013 | Conference Paper |

HTML

Quantum dots (QDs) are interesting material options for the lighting and display markets, however, several limitations have limited QD applicability. This tutorial will review both limitations and breakthroughs in QD performance that has led to their recent commercialization in both of these markets.Show More

HTML

We report on wavelength-variable lasing from optical gain media composed of colloidal quantum-dots (CQD) thin films across the visible spectrum. Exploiting single exciton gain enables amplified spontaneous emission (ASE) and vertical cavity lasing at very low optical pump thresholds. The average number of exciton per CQD at the ASE threshold is ;~ 0.8, which significantly reduces losses from e...Show More

A new nanocomposite material was created by embedding colloidal CdSe-based quantum dots (QDs) within single crystal nanoporous gallium nitride (GaN) host. High efficiency luminescence and wavelength-engineered ability of colloidal QDs combined with high performance of nitride blue LEDs suggest this nanomaterial's potential for solid state lighting.Show More
