Energies of reflectivity minima versus the wavevector for samples 1 to 3 (a to c; respectively). The dashed lines correspond to the TDBC absorption maximum 590 nm (2.1 eV) and the red light (632.8 nm) energy (1.96 eV). The full lines are calculated polaritons energies. The thickness of Ag and TDBC-PVA layers is indicated on each figure.
