We previously reported that lead iodide-based two-dimensional layered hybrid perovskite(2D LHP) thin films can be fabricated by immersing an octadecylamine (ODA) Langmuir–Blodgett (LB) film in a PbI₂/HI aqueous solution. We also demonstrated the multiple-quantum-well (MQW) polariton effect, which arises when the exciton energies of different quantum wells in an MQW structure are precisely matched. In the present study, we found that lead bromide- and lead chloride-based 2D LHP ultrathin films fabricated by a similar method also exhibit high structural order. The structural and optical properties of these films are reported.
