Using colloidal chemistry approaches, we synthesize nanocrystals of different materials with variable sizes, shapes and compositions. We focus on infra-red emitting II-VI semiconductor nanocrystals; carbon dots, perovskite nanocrystals and metal nanoclusters emitting in the visible spectral range.
We widely apply advanced photoluminescence spectroscopy to study light emission, energy transfer and charge separation in composite structures containing those nanoparticles, and explore their different applications such as LEDs, displays, photodetectors, and batteries.

A new long-awaited review on HgTe QDs
Our latest review paper "The Rise of HgTe Colloidal Quantum Dots for Infrared Optoelectronics" is finally out! This is a joint effort made with Emmanuel Lhuillier, Christophe Delerue, Philippe Guyot-Sionnest, Xin Tang, Sean Keuleyan, and Sandrine Ithurria groups. It also marks the culmination of our Steve Kershaw's efforts in this research field. This seminal paper is open access.
