High pressure and high temperature induced polymerization of C60 quantum dots
(a) IR spectra of C60 FWS and C60 QDs. (b) Raman spectra of C60 FWS and C60 QDs using 514 nm laser excitation. The inset shows the linear amplification at 200–580 cm−1. The marked stars represent the typical IR and Raman peaks of C60.
