dynamics reveal a dark ground state in both CsPbBr3 and CsPbI3 NCs with corresponding bright-dark exciton splitting being 4.2 meV and 6.5 meV, respectively. In CsPbI3 NCs, very interesting anomalous polarization [...] three kind of semiconductor nanocrystals (NCs), i.e. CdSe, CuCl and all-inorganic perovskite (CsPbBr3, CsPbI3) are studied, which help to understand the exciton fine structures and related interactions in each [...] g-factors in CuCl NCs are investigated comprehensively, where the degree of circular polarization of the Z3 exciton emission is found to increase linearly with the magnetic field at low temperatures up to 8 T …
