Surface plasmon resonance of electrochemically deposited Au-black

Au-black, a kind of gold nanostructure, was electrochemically deposited on a Au-vapor-deposited glass plate, and its optical properties were evaluated with a surface plasmon resonance (SPR) measurement system. The Au-black was found to exhibit an extraordinary high resonance angle (minimum reflectance angle) compared to that of the Au-vapor-deposited glass plate. We proposed a five-layer model, which consists of glass, Cr, Au, Au-black, and solution layers, to explain the high resonance angle of the Au-black plate. The calculation was based on the Fresnel formulas extended for multilayers. When the Bruggeman formula was used to obtain a refractive index of the Au-black layer, the numerical simulation could qualitatively explain the experimental observations. The curve fitting method by the five-layer model enabled us to simultaneously estimate the thickness of the Au-black layer and the volume fraction of Au in Au-black.
