a Photoluminescence (PL) of CsPbBr3 NPLs as a function of time and wavelength. b PL of CsPbBr3 NPLs + PDI hybrid as a function of time and wavelength. c Comparison of the temporal decay of the fluorescence of CsPbBr3 NPLs (4ML) and CsPbBr3 NPLs + PDI hybrid at 460 nm. The fluorescence quenching in CsPbBr3 NPLs + PDI hybrid may be a result of electron transfer to PDI.
