Hyperfine versus exchange interaction in the spin dynamics of spatially indirect excitons in CsPbI${}_3$ perovskite nanocrystals

Timur S. Shamirzaev, Nataliia E. Kopteva, Dmitry S. Smirnov +7

We study the dynamics of recombination, optical orientation, and optical alignment of excitons in ensembles of CsPbI${}_3$ nanocrystals (NCs), synthesized in a glass matrix. In lar…
