Abstract

Ultraviolet photoelectron spectra of Lu@C₈₂(I), Lu ₂@C₈₂(II) and Lu₂C₂@C ₈₂(II) were measured. The spectral onsets (E_onset) of these fullerenes indicate their semi-conductive nature. While their deeper valence band UPS derived from the σ-electrons of C₈₂ cage are almost identical, the upper valence band UPS of Lu@C₈₂(I) is significantly different from those of Lu₂@C₈₂(II) and Lu₂C₂@C₈₂(II). Lu4f_7/2 and Lu4f _5/2 levels are observed in the UPS, which could be the first finding of the inner levels derived from the encapsulated species. These levels deviate slightly when encapsulated species change, which could be due to the difference in the amounts of electrons on Lu atom(s).
