Quasi-2D halide perovskites combine large oscillator strengths, high exciton binding energies and tunable emission spectra. Using mechanically exfoliated (BA)₂(MA)₂Pb₃I₁₀ crystals embedded in a tunable open optical microcavity, we access a regime of ‘very strong' coupling and observe room-temperature exciton-polariton condensation.
