- Abstract
Single-walled carbon nanotubes are filled with a cerium organometallic compound. Using core-level excitation spectroscopy we study the electronic structure of specific atoms in this complex compound. From X-ray absorption spectroscopy we show that the electronic configuration of cerium is nearly trivalent. Resonant photoemission spectroscopy provides further details of the valence electronic properties of cerium as well as of carbon. Thermal annealing modifies the chemical identity of the filling that varies the electronic interactions between the nanotubes and filling material.
