Temperature driven charge transfer process in quantum confined two-dimensional Mn-doped CsPbBr3 perovskite nanoplatelets

Abstract

A temperature dependent transient absorption study has been demonstrated for Mn2+ doped CsPbBr3 nanoplatelets. At 5 K, charge transfer is suppressed due to the trapping of charge carriers in defect states. By contrast, at 300 K, an efficient charge/energy transfer process is observed as the thermally active carriers become de-trapped from the defect states upon strong exciton–phonon coupling.
