Impacts of passivation on thermal quenching characteristics of quasi-2D perovskite (IMAGE)
Caption
a Thermal quenching and recovery processes of quasi-2D perovskite films under white and UV light. Temperature-dependent PL spectra of perovskite films b without, c with bulk, d with surface, and e with dual passivation. f Integrated PL intensities, g wavelength and h FWHM of PL peaks for perovskite films without and with dual passivation. Inset of (h) is the diagram of exciton-phonon interaction and nonradiative recombination promoted by defects.
