The molecule is embedded in a\nPMMA matrix that is spin coated between the metallic mirrors. Transmission, reflection\nand luminescence measurements are performed to characterize the cavities and films.\nMicrocavity samples with resonances at the molecule\u2019s absorption maximum of 375 nm\nand Q factors between 4.3 and 18.7 depending on the mirror thickness were demonstrated.\nCouplings from 0 up to 195 meV between polariton branches are shown in the transmission\ndispersion. Luminescence measurement detects fluorescence of the proton transferred form\nof the molecule around 610 nm from film both with and without cavity. The intensity of\nthe fluorescence is found to increase with stronger coupling compared to the absorption of\nthe hybrid state.\nThe evidence of strong coupling is found to be insufficient in this study as the Rabi splits\nare not large enough compared to the line widths of the peaks.
