Abstract:
The preparation of C60-doped silica aerogels by the sol-gel process is described in this article. Fourier transfer infrared spectra, time-of-flight mass spectroscopy, and transmission electron microscopy showed that C60 was incorporated into silica aerogels, and the C60 structure was retained in the preparation process. The C60-doped silica aerogels emitted intense visible light (2.10 eV) under Ar+ laser (488 nm) excitation at room temperature, and the photoluminescence peak was “blueshifted” when compared with C60’s. The blueshift is explained based on a quantum confinement effect.
