Optical emission around an evaporation source of carbon (and metal/carbon composite) has been studied. For the evaporation of pure graphite, C2 bands and C and C+ lines were observed. When metal (La or Sc)/carbon composite was evaporated, many emission lines due to neutral and ionized metal atoms were observed in addition to the C2 bands and C and C+ lines. An effect of polarization force induced by metal ions on the nucleation of metallo-fullerenes is noted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
