Highly Sensitive Local Surface Plasmon Resonance in Anisotropic Au Nanoparticles Deposited on Nanofibers

Figure 4

Incident angle dependences of LPR extinction intensity observed in AuNF100 (broken lines), AuSPF (solid lines), and 20 nm diameter Au nanospheres chemically immobilized on a BK7 glass substrate (dotted lines). For each sample, solid circle (●) and square (□) show the LPR extinctions in p-polarized and s-polarized extinction spectra, respectively. The lines are guides for the eye.
