Based on these XPS records for Cd 3d, S 2p, O 2p, C 1s, which are characteristic of CdS and CNTs, we confirmed the successful formation of the CdS/SWNTs.
It is noteworthy that the atomic content of 71.7% of carbon, viz. much higher than that of
oxygen, suggested that CNTs were oxidized somewhat yet retained their inherent nature through their purification process.
