a TA spectra at different timescales, b TA spectra at different wavelengths as a function of delay time, c PL spectra at distinct timescales, and d PL decay curve probed at selected wavelengths for <n> = 3 perovskites. Comparison of e initial time PL intensities and f PLQYs as a function of the photoinjected carrier density between 3D and quasi-2D perovskite films.
