Trajmar, S.; Wang, S.; Man, K.F.; Khakoo, M.A., 1993, "Fluorescene of Buckminsterfullerenes: UV Emission of C60+ and C70+", https://hdl.handle.net/2014/34907, UNKNOWN, JPL Open Repository
We report the first observation of UV luminescence from gaseous C60+ and C70+ buckminsterfullerenes. The emission features appear in the 275 to 340 nm wavelength region and originate from radiative decay of the excited ionic species. |
