摘要：

Optical reflectivity spectra were measured for the superconducting fulleride K3C60 and for pristine C60 single crystals in the wavelength region from infrared to ultraviolet. High-quality samples of K3C60 with flat surfaces were grown for this purpose by cosublimation of both C60 and potassium metal. A sharp plasma edge was found at 0.73 eV in the reflection spectra of K3C60. A quantitative discussion is given on the conduction band structures based on the band parameters derived from a spectral shape analysis in terms of the Drude-Lorentz model.
