Abstract

Ultrathin nanoporous gold films (NPGF) with a thickness of approximately 50 nm were fabricated via electrochemical dealloy method. The morphology of NPGF was evaluated with a parameter of surface roughness. SEM results demonstrate that the fabrication of NPGF with different roughness factors can be achieved by controlling the circles of cyclic voltammetry. UV-Vis spectra indicate that the localized surface plasmon resonance (LSPR) of NPGF is affected by the roughness of NPGF. With the optimal roughness factor, NPGF displays a linear relationship between the ethanediol concentration and the absorbance intensity at λ = 450 nm. The LSPR effect of NPGF presents potential applications in quantitative detection of solution concentration.
