APL excitation configuration and APL/extinction spectra.

(a) Light path configuration for sample excitation and APL signal collection. The focused Gaussian laser beam was p−polarized. (b) Left panel: APL spectra excited by laser of three different wavelengths. Hollows in the spectra are caused by notch filters. Right panel: Extinction spectra of the sample. Transverse and longitudinal SPR bands locate at 2.37 eV and 1.47 eV, respectively.
