Abstract
Single-walled carbon nanotubes with designed quantum defects are prepared and characterized. The photoluminescence (PL) of the nanotubes can be modified by thermal treatment from 1215-1224 to 1249-1268 nm. Theoretical calculations suggest that the change in the PL spectra by thermal treatment can be explained by isomerization from kinetic to thermodynamic products.
摘要
设计量子缺陷的单壁碳纳米管被制备并进行了特性分析。通过从 1215-1224nm 到 1249-1268nm 的热处理，可以改变纳米管的光致发光（PL）。理论计算表明，热处理导致的 PL 光谱变化可以用从动力学产物到热力学产物的异构化来解释。
