Figure 3. (a), (b) Polarization dependence of the PL spectra of the AuNFs under excitation at wavelengths of 532 nm (black) and 633 nm (red) for two representative AuNFs. (c), (d) The PL imaging patterns of the same AuNFs under different incident-light polarizations.

The blue arrows indicate the directions of the excitation polarizations.
