关于此文的PL spectrum的分析,在此向各位求教。 论文来源Adv.Funct.Mater. 2008,18,1-7 论文对此图的解析: The individual dissolution of the SWNTs with PBI was proved by the photoluminescence (PL) observation presented in Figure 5, in which we see strong two-dimensional (2D) PL spots from the SWNTs with chirality indices of (7,6) and (9,4). 备注:supernatant 1 是指polymer和SWNTs溶解于DMAc溶液中,然后通过高速离心机离心得到的上层溶液。此作者认为在supernatant1中SWNT是通过物理吸附与PBI(一种刚性的液晶polymer)很好的结合的,通过PBI包覆SWNTs来消除SWNT之间的团聚现象。此图就是对supernatant 1 的PL spectrum。
