Angle-resolved reflection and emission spectra of metal gratings consisting of subwavelength grooves and immersed into rhodamine B and rhodamine 19 solutions are presented. The measured reflection and emission dispersion diagrams reveal the surface plasmon polaritons positions and strong plasmon-mediated emission enhancement, respectively. The same grating could be easily reused for the characterization of different dye molecules.
