Since their first synthesis in 2015, perovskite nanocrystals have emerged as very promising nano-emitters for optoelectronic applications due to their excellent optical properties and affordable chemical synthesis. Although these new nano-emitters are mainly studied in aggregates, the study of individual perovskite nanocrystals has shown a bright and stable single photon emission (with reduced blinking effects) up to room temperature, paving the way for applications in quantum photonics.

Our team has been studying the fundamental optical properties of inorganic perovskite nanocrystals at the individual scale through advanced confocal spectroscopy and quantum optics experiments. The coupling of individual perovskite nanocrystals to original photonic structures, such as the fibered microcavities developed in the team for carbon nanotubes in collaboration with the LKB, will be used to enhance and control light-matter interaction in these systems and thus to highlight the effects of quantum electrodynamics in cavity with accessible emitters synthesized in solution.
