Abstract
The optical properties of the metallized tips used in tip-enhanced Raman spectroscopy (TERS) are vital to resonance enhancement. A white-light scattering-spectrum measuring setup based on total internal reflection microscopy is developed to characterize the optical responses of the metallized tips. The scattering spectra of the Ag-coated optical fiber tips are measured as a demonstration of the methodology and the performance of the setup. A prominent resonance band of
