Using colloidal chemistry approaches, we synthesize nanocrystals of different materials with variable sizes, shapes and compositions. We focus on the infrared-emitting semiconductor nanocrystals, ternary quantum dots, carbon dots, perovskite nanocrystals, and metal nanoclusters emitting in different spectral ranges.
We widely apply advanced photoluminescence spectroscopy to study light emission, energy transfer, and charge separation in composite structures containing those nanoparticles, and explore their application in LEDs, displays, photodetectors, and batteries.

New approach boosts efficiency of perovskite light-emitting diodes
Our group has developed a novel method to produce FAPbBr3 perovskite films with an ultralow trap density of 1.2×1010 cm−3, significantly enhancing the performance of LEDs. This advancement resulted in green perovskite LEDs achieving a brightness of approximately 312,000 cd/m2, a half-lifetime of 350 hours, and a power conversion efficiency of 15.6%.
