Challenge to arrangement control of heat-fragile fullerene by droplet jet plasma

为了控制热脆性氮原子内嵌富勒烯（N@C60）的排列，我们利用液滴喷射等离子体将N@C60封装到碳纳米管（CNT）中。首先，我们将空的C60溶解在甲苯中，并使用等离子体将C60照射到CNT上。因此，我们已经成功地将C60离子封装到CNT中。第二，以与C60相同的方式将高浓度的N@C60照射到CNT上，然而，在CNT中不能检测到N@C60。通过研究紫外光（UV）对N@C60的影响，发现N@C60被UV分解与UV照射时间成比例，因此，我们已经确定CNT中不存在N@C60的原因是N@C60被等离子体发射的UV照射而不稳定。

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.
