Extended Data Fig. 7

a, Absorption spectra of CsPbBrI2 film with and without CQDs embedded. b, PL quenching at perovskite emission range. When CQDs are embedded, the PL signal from perovskite is completely quenched, showing an efficient carrier transfer from the matrix to the CQDs. c, PL quantum yield of CQD-in-matrix films at different CQD ratios.
