dc.description.abstractGood understanding of carrier generation and recombination is crucial for applications in LEDs, lasers, single photon sources and so on. In this work, we studied and compared charge generation and recombination processes of CsPbBr3 QDs and microcrystals (MCs) in order to obtain clearer pictures for their photoluminescence. Power dependent photoluminescence experiments show that excitation species and recombination process are quite different in CsPbBr3 QDs and MCs, where the MCs contain non-radiative dark states resulting a superlinear power dependence of the PL intensity at low excitation power while the QDs materials show linear dependence. At high excitation power, trions are generated in the QDs samples.en
