研究了钼团簇包覆对单壁碳纳米管（SWNTs）光学性质的影响。详细的透射电子显微镜观察表明，包裹在单壁碳纳米管的空心内的钼团簇表现出短棒状结构的形式，表明团簇在受限的纳米空间内生长。的上移G-带频率以及淬灭的光致发光和吸收信号表示的调制单壁碳纳米管的电子性质所造成的纳米管和钼簇之间的强耦合相互作用。
Changes in the optical properties of single walled carbon nanotubes (SWNTs) caused by the encapsulation of molybdenum (Mo) clusters were investigated in the current research. Detailed transmission electron microscope observations showed that the encased Mo clusters within the hollow core of SWNTs exhibited in the form of short rod-like structure, indicating the growth of the clusters within the confined nano space. The upshifted G-band frequency as well as the quenched photoluminescence and absorption signals signified the modulation in the electronic properties of SWNTs caused by a strong coupling interaction between the nanotube and the Mo clusters.
