Visualizing Disorder-Induced Photoluminescence Quenching in Sn–Pb Perovskites

Caption

This schematic illustrates how static disorder (defects and impurities) and dynamic disorder (phonon interactions) affect carrier dynamics in tin–lead alloyed perovskite nanocrystals. As temperature rises, increased electron–phonon interactions amplify non-radiative trap states, suppressing photoluminescence (PL) efficiency.
