(Double) Perovskite Nanocrystals

Our research delves into innovative metal-halide perovskite nanocrystals, including both lead-based and lead-free systems, particularly double perovskites. Those double perovskites hold unique crystal structures and a distinctive photoluminescence mechanism based on self-trapped excitons. These materials are highly responsive to structural and electro-optic modifications, due to their soft, adaptable lattices and strong exciton-phonon coupling.

Leveraging our advanced high-throughput robotic synthesis platform, we have developed post-synthetic modification processes such as cation exchange. This enables rapid screening and characterization of a wide range of compositions, including compositions that never previously reported.
Additionally, we explore surface chemistry through ligand exchange, focusing on improving photoluminescence quantum yield (PLQY) and enhancing material stability.
