摘要: Abstract Surface plasmons (SP) or surface electromagnetic waves were excited at the silver-aqueous electrolyte interface with visible light using an attenuated total reflection arrangement. SP resonances observed as a function of potential in perchlorate and halide electrolytes. At fixed wavelength, resonance shifts to smaller wave vector electrode becomes more positive. Various contributions this shift will be discussed: changes electron density metal surface, ion adsorption optical properties ionic double layer. Halide reflectivity: curve negative potentials.
