dc.description.abstractLayered Ruddlesden-Popper-type (2D) metal-halide perovskites exhibit markedly increased exciton binding energies, exceeding 150 meV, compared to their 3D counterparts. Many-body physics, enabled by Coulomb interactions, play a strong role and raises the biexciton binding energy to 50 meV. We report photoluminescence at a range of temperatures and carrier concentrations in thin films of the layered perovskite material (C12H25NH3)2PbI4. We directly observe biexcitons up to a sample temperature of 225 K. We construct an optical microcavity (comprising a distributed Bragg reflector and a metal mirror), with photonic resonances tuned near to the biexciton energy. We observe optically-pumped biexciton lasing up to 125 K, with a threshold peak excitation density of 5.6 × 1018 cm-3. The demonstration of biexciton lasing above liquid nitrogen temperatures is a crucial step for the application of layered perovskites in photonic applications.
