(color online) (a) Comparison of PL (532 nm excitation) and DF scattering spectra of gold nanorod, gold nanotriangle, and gold nanodisk with a typical size of 80 nm.^[14] (b) Comparison of the PL normalized by DF scattering spectra of three gold nanostructures and the PL from gold film. (c) and (d) Comparison of measured and fitted PL (532 nm excitation) and DF scattering spectra of dolmen-like plasmonic nanostructures. (e) A simple three-step model to describe the PL process in the dolmen-like plasmonic nanostructure. (f) Peak and dip positions of PL from the dolmen-like plasmonic nanostructure can be explained by the convolution of the PRF of electrons (solid blue curve) and the DoPS of intrinsic LSPR modes (dotted green and purple curves).^[15]
