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.
