Properties of fluorescent gold nanoclusters. (A) A scanning electron microscopy (SEM) image of synthesized gold nanocluster particles (Bar = 5 nm). (B) Absorption and photoluminescence spectra for gold nanoparticles. nanoAu itself is a fluorescent molecule, with emission at 674 nm. Abs, Absorption; PL Photoluminescence.
