摘要：
Fluorescence properties of C-60 nanoparticles produced by sonication in pyridine have been systematically investigated. The fluorescence emission of C-60 is dependent on the particle size. A red shift of emission maximum from 424 to 468 nm originates from the average size increase caused by strong interaction among C-60 molecules in nanoparticles. In addition, it is also confirmed that the emergence of broad fluorescence emission band in the 550-570 nm region is ascribed to C-60 nanoparticles aggregation. (C) 2013 Elsevier B.V.
