| Research Abstract |
For the purpose of arrangement control of heat-fragile nitrogen-atom endohedral fullerene (N@C60), we have performed the encapsulation of N@C60 into carbon nanotube (CNT) using a droplet jet plasma. First, we dissolved empty C60 in toluene and irradiated the C60 to CNT using the plasma. As a result, we have been successful in encapsulating the C60 ions into CNT. Second, highly-concentrated N@C60 was irradiated to CNT in the same way as C60, however, N@C60 cannot be detected in CNT. By investigating the effect of ultraviolet light (UV) on N@C60, it is found that the N@C60 was decomposed by the UV in proportion to the UV irradiation time, and therefore, we have identified the causation of absence of N@C60 in CNT as the instability of N@C60 by the irradiation of UV emitted from the plasma.
