It is demonstrated not deleterious to the sensing signals of the nanosphere. The proposed nanocomposite provides an interesting localized surface plasmon resonance (LSPR) sensor with quadratic response, which refractive index (RI) sensitivity is revealed to increase with the RI both of its surrounding and local environment. The differences between the LSPR peak positions of the nanocomposite measured from far-field and near-field spectra are discussed, too. It is believed to shed light on the future applications in surface enhanced Raman spectroscopy, biochemical sensing, and detections.
