- Аннотация: Composite photonic crystal films with Au nanoparticles were obtained by inversion of opal templates using a photocurable resin followed by double impregnation with a gold colloidal solution. The surface enhanced Raman scattering (SERS) signal was analyzed as a function of the photonic stop band spectral position using the methylene blue dye as a test compound. It was shown that a coincidence of the photonic stop band center with the Raman laser wavelength leads to an enhancement of Raman scattering by a factor of 20. The overall enhancement factor was more than 105 in this case, and the detection limit for methylene blue in solution was on the order of 10-7 M. The combination of large and reproducible enhancement factor, low analyte consumption and moderate gold concentration (~0.6 μg/mm2) makes our samples very promising for use as Raman sensors.
