    • When excitation wavelengths of λ, 330 and 400 nm are used, the quantum yields are close to 6.0 × 10-4 (i.e, identical to that of the C60 reference) in toluene and THF. With λex, 435 nm, the quantum yield is somewhat lower (3.6 × 10-4, and with an excitation wavelength of λ =485 nm, the quantum yields are around 3.0 × 10-4, 2.5 × 10-4, and 2.0 × 10-4 in toluene, THF, and benzonitrile, respectively. Further support for this proposed energy transfer mechanism comes from the observation that using excitation at the C60 fluorescence maximum (i.e, λ=715 nm) gives rise to a spectrum that is in reasonable agreement with the ground-state absorption spectrum, including the λ, 435, 485, and 690 nm features that are characteristic of both constituents. However, because the quantum yield for the C60 emission following irradiation o
