Thermal Evolution of the Structure and Luminescence of the Hybrid-Cation-Stabilized [(4AMTP)PbBr₂]₂PbBr₄ Layered Perovskite

My contributions:

• Analyzed low-temperature (8–300 K) single-crystal and powder X-ray diffraction (SCXRD, PXRD) data to evaluate the phase behavior of the 2D perovskite, showing complete suppression of phase transitions and enhanced structural rigidity from the hybrid A-site cation.
• Performed variable-temperature steady-state and time-resolved photoluminescence spectroscopy to map exciton dynamics, uncovering the interplay between bright and dark excitons.
