SERS signals at various structures formed by silver nanowires are investigated using confocal Raman microscopy to understand the effect of the density of interstitials on SERS signal. Spatial and spectral dynamics and heterogeneities in both photoluminescence and SERS are compared. Incident laser polarization angle dependence of the SERS intensity and its spatial distribution were revealed using SERS imaging. SERS enhancement capability of interstitials formed by silver nanostructures can be used to understand interfacial charge transfer dynamics at the surface of single crystal anatase TiO2 synthesized using the hydrothermal reaction. By combining photoelectrochemistry and SERS, the charge transfer mechanism and the preferred transfer pathway within the crystal can be resolved.
