Lattice distortion of perovskite quantum dots induces coherent quantum beating
Sep 2022, phys.org
Quantum beating - Using ensemble-level femtosecond polarized transient absorption, the researchers observed clear bright-exciton fine structure splitting in solution-processed CsPbI3 perovskite quantum dots, which is manifested as exciton quantum beats (periodic oscillations of kinetic traces).
