We successfully prepared optically high quality thin film of lead halide-based layered perovskite by Langmuir-Blodgett technique. Simulation by using refractive indices of the LB film demonstrates that large Rabi splitting of 130 meV is observed when the LB film is incorporlate into microcavity. The large Rabi splitting suggests that the room temperature cavity polariton laser using the LB film is possible.
