Abstract

Fluorescent gold nanoparticles with high quantum yield are highly desirable for optical imaging in the fields of biology and materials science. We investigate the one-photon photoluminescence (PL) properties of individual gold nanobipyramids (GNBs) and find they are analogous to those of the extensively studied gold nanorods (GNRs). By combining PL and atomic force microscopy (AFM) measurements with discrete dipole approximation (DDA) simulations, we obtain the PL quantum yield of single GNRs and GNBs. Compared to GNRs in the similar surface plasmon resonance range, the PL quantum yield of GNBs is found to be doubled. The stronger field intensity around GNBs can explain their higher PL quantum yields. Our research would provide deeper understanding of the mechanism of PL from gold nanoparticles as well as be beneficial for finding out optical imaging labels with high contrast.
