摘 要:The LSPR is an optical phenomenon generated by collective oscillations of the electron gas inmetal nanostructures surrounded by a *** LSPR spectral position is highly dependent on the size or shape of *** gold nanoring arrays are used in LSPR sensors due to their near-infrared resonance wavelength demonstrated with high *** use the discrete dipole approximation method to study the extinction spectra of different shape of gold nanorings and the relationship between the extinction peak redshift and the parameter of gold *** QCM is used to measure the amount of added mass to the electrodes which is linearly related to the resulting shift in resonant *** develop a new kind of sensor combined with LSPR and QCM *** sensor presents a good sensitivity in liquids of different dielectric constant.
