Abstract
In the paper, gold nanoparticles film is fabricated based on nanolithorgraphy. The nanostructure and the optical properties are studied by SEM and spectroscopy. We design a spectroscopy acquisition system, gain the peak absorption wavelength by fitting the data collected, then we analyze its localized surface plasmon resonance effect by experiments of sucrose with different concentration. It shows a red-shift of peak absorption wavelength when the refractive index of external medium of gold nanoparticles film changes.
