A nitrogen atom encapsulated fullerene (N@C60) and an azafullerene (C59N), which have characteristic features as novel materials for electronic devices, are selectively synthesized by a plasma-ion irradiation method. It is found that the optimum energies of irradiated ion for C59N and N@C60 syntheses exist around 40-50 eV and 50-200 eV, respectively. The massspectrum peak originated from N@C60 is observed using laser-desorption timeof-flight mass spectrometry. The purity of N@C60 to C60 in the nitrogenfullerene compounds after ion irradiation is about 10-3-10-2 %, which can be improved by high performance liquid chromatography.
