单壁碳纳米管 (SWCNT) 的光学跃迁能 (E-ii) 受到溶剂和吸附分子产生的局部环境的影响。对各种介电介质中 SWCNT 光致发光 (PL) 能量的分析用于阐明 E-ii 位移的半经验标度关系和经典溶剂化显色形式的纳米管结构特性。 SWCNT Kataura 图针对统一的介电常数进行了校正，并与缩放结合使用，以准确描述各种介电介质中的 PL 能量变化。 (C) 2007 年美国物理研究所。
The optical transition energies (E-ii) of single-walled carbon nanotubes (SWCNT) are influenced by the local environment created by solvents and adsorbed molecules. Analysis of SWCNT photoluminescence (PL) energies in various dielectric media is used to elucidate a semiempirical scaling relation for E-ii shifts and nanotube structural properties from a classical solvatochromic formalism. The SWCNT Kataura plot is corrected for a dielectric constant of unity and used in conjunction with the scaling to accurately describe PL energy shifts in a broad range of dielectric media.
