Abstract

X-ray-amorphous anodic titanium dioxide is proposed as a carrier of nanostructured silver with a controllable surface roughness for the creation of composite films with an effect of the surface plasmon resonance in the visible region for the spectroscopy of giant combinational scattering (GCS). A comparative analysis of GCS composites obtained by different methods of silver immobilization at the surface of a semiconductor TiO2 (photolysis of silver nitrate (I), magnetron sputtering, and thermal decomposition of ammonium silver complex (I)) has shown a substantial dependence of the functional characteristics on preparation history in the case of model analytes with different spectral characteristics, i.e., dyes of rhodamine 6G and methylene blue in low concentrations of 1 × 10−8 mol/L by an aliquot volume of less than 10 μL.
