Quantum dots may lead to cost-effective mid-infrared light sources and sensors

By Lisa McDonald / October 6, 2023

Quantum dots are emerging as a cost-effective materials system for both emitting and detecting mid-infrared light. Philippe Guyot-Sionnest’s group at the University of Chicago is working on developing this technology, and their latest paper describes a quantum-dot-based light source that is as efficient as current commercial devices.

Manipulate light on the nanoscale: Proposed quantum dot–graphene scheme improves conversion of light into surface waves

By Lisa McDonald / December 11, 2020

Surface plasmon polaritons are a type of surface wave that, when harnessed, show potential to improve various processes that take place on the nanoscale, such as molecular imaging. Researchers from two places in Russia propose a new scheme using quantum dots and graphene to more efficiently convert light into surface plasmon polaritons for use in such applications.
