摘要	Carbon-coated YC(2) nanocapsules were prepared by arc-discharging bulk yttrium in methane. The core/shell structure was obtained, where a polyhedral crystalline YC(2) core was coated by defective graphite shell with size of 1-3 turn. The hydrolyzing of the zero-dimensional superconductors YC(2) was controlled by the shell. The magnetic properties of the carbon-coated YC(2) nanocapsules show that the dimensional effect has a very small influence on its superconducting transition temperature. The Raman spectrum of the carbon-coated YC(2) nanocapsules shows that the shell is defective graphite and also suggests that the aberrance structure of the carbon shell is related to the zone-edge vibration of the YC(2) core.
