Fine Structure of Excitons and electron-hole exchange energy in Polymorphic CsPbBr3 Single Nanocrystals Julien Ramadea, Léon Marcel Andriambariarijaonaa, Violette Steinmetza, Nicolas Goubeta, Laurent Legranda, Thierry Barisiena*, Frédérick Bernardota, Christophe Testelina, Emmanuel Lhuilliera, Alberto Bramatib, Maria Chamarroa. All inorganic CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) belong to the novel class of confined metal-halide perovskites which currently arouses enthusiasm and stimulates a huge activity due to outstanding properties across several fields of optoelectronics. A deep knowledge of the band-edge excitonic properties in those materials is thus crucial to further optimize their performances.
