Up to this point, we have been considering the absorption properties of Au nanoparticles and the significance of Cabs in colorimetric or photothermal applications. However, colloidal Au particles are also famous for resonant light scattering, which depends on CJca.109,110 The earlier description of C, is dominated by Cabs and intended only for smaller nanospheres (r < 20 nm). Cext is more correctly described as the sum of Cabs + Csca ...

The form of the result (18.23 ) suggests an interpretation of resonance light scattering as a 2-stage process—preparation of the intermediate level s followed by emission out of this level. We will see, however, that such a picture is too simplistic. For example, if several intermediate levels s contribute to the light scattering an... 

These contradictory results led Jonkman et al.21 to propose that non-resonant light scattering (NRLS) was responsible for the fast component. NRLS would yield decays that basically consisted of Raman-Rayleigh-scattered laser light together with the slower fluorescence decay. It would look like biexponential decay. Experiments where the laser was purposely detuned from the rotational line seemed to confirm their ideas.21...

To obtain reliable experimental data and to correctly interpret them, we used such physicochemical and analytical techniques as dilatometiy, viscometiy, UV and IR spectroscopy, electronic paramagnetic resonance, light scattering spectroscopy, electron microscopy, and gas-liquid chromatography. To analyze the properties of polymeric dispersions, the turbidity spectrum method was used, and the efficiency of flocculants was estimated gravimetrically and by the sedimentation speed of special suspended imitators (e.g., copper oxide).
