Abstract:
Rhodamine 6G is spin-cast onto gold surfaces and the reflectance, emission, excitation, and SERS spectra are reported. Electron microscopy shows that the particle sizes of the gold are uniform for all preparations. Reflection spectra demonstrate the spectroscopic signature for Rh6G aggregates for thicker films and that the gold plasmon band shifts due to the refractive index change on the surface. The intensity of the SERS spectra increases with increasing surface coverage but the change is nonlinear between submonolayer and multilayer surface...
Excerpt:
The reflection spectra were obtained using a Filmetrics F40 microscope with a tungstenhalogen light source from 4501000 nm. Raman spectra were obtained on an Agiltron PeakSeeker spectroscope with a 785 nm laser set at 300 mW and an integration time of 30 seconds...
