摘要/ Abstract摘要：在氮气和氨气的混合作用下，对樟脑进行热解制备了含氮碳纳米管，并将其封装在沿管轴有规律分布的纳米容器中。空间分辨电子能量损失光谱（EELS）分析表明，纳米胶囊内含有N2分子。石墨化良好的壁可以被电子照射击穿，从而部分释放N2。这一过程伴随着无定形CNx岛的形成，时间分辨EELS序列的动态记录和分析证明了这一点。这种局部原位电子束纳米加工和纳米分析为可控地生产新型纳米器件提供了一种方法。
Abstract:Carbon nanotubes containing nitrogen encapsulated in nanocontainers regularly distributed along the tube axis, have been produced by pyrolysing camphor in the presence of a mixture of nitrogen and ammonia gas. Spatially resolved electron energy-loss spectroscopy (EELS) analysis reveals that N2 molecules are contained within the nanocapsules. The well-graphitized walls can be punctured by electron irradiation, thus partially releasing N2. This process is accompanied by the formation of amorphous CNx islands, as demonstrated by dynamic recording and analysis of time- resolved EELS sequences. Such local in situ electron beam nanomachining and nanoanalysis provide a method for producing under control new classes of nanodevices.
