We synthetize some new perovskite thin layers: p-fluorophenethylamine tetraiodoplumbate pFC(6)H(4)C(2)H(4)NH(3))(2)PbI(4) perovskite molecules, included in a PMMA matrix. We report on the optical properties of the perovskite doped PMMA thin layers and we show that these layers are much more stable under laser illumination and present a smaller roughness than the spin-coated (C(6)H(5)C(2)H(4)NH(3))(2)PbI(4) layers. These new layers are used as the active material in vertical microcavities and the strong-coupling regime is evidenced by a clear anti-crossing appearing in the angular-resolved reflectivity experiments at room temperature.
