Discerning between Exciton and Free-Carrier Behaviors in Ruddlesden–Popper Perovskite Quantum Wells through Kinetic Modeling of Photoluminescence Dynamics

Two-dimensional (2D) Ruddlesden–Popper (RP)-layered lead halide perovskites have recently emerged as a more stable alternative to their three-dimensional (3D) counterparts while also exhibiting int...
