| Popis: | Self-assembled photonic crystals grown from different colloidal sizes are coated with gold nanoparticles preferentially on their surface. The effect of localized surface plasmon resonance and the photonic stopband on the Raman scattering from these crystals is analyzed from the angle-dependent scattering measurements. The coupling of photonic and plasmonic modes at the surface of the photonic crystal is verified by measuring the increment in Raman scattering from the crystals containing the gold nanoparticles, and this increment is found to follow the spectral trend of localized surface plasmon resonance. |
