The absorption spectra of C 60 doped in PMMA film and C 70 doped in PMMA film both have been recorded, and each of their absorption spectra in solution has also been measured. Those experiment results show that the interaction between PMMA and fullerene is very weak and the absorption curve of fullerene doped in PMMA film is almost in consistent with that in solution. The absorption peaks of C 60 doped in PMMA film move toward longer wavelength than those in solution, but which of C 70 move toward shorter wavelength. Possible reasons for these phenomena have been discussed. 富勒烯 有机玻璃 吸收光谱 Fullerene polymethyl methacrylate absorption spectra O433.51 武汉市科委重点科技攻关计划资助 1996-06-01 2021-04-01 6
