Abstract
The optical transition energies ( E i i ) of single-walled carbon nanotubes(SWCNT) are influenced by the local environment created by solvents and adsorbed molecules. Analysis of SWCNTphotoluminescence(PL) energies in various dielectric media is used to elucidate a semiempirical scaling relation for E i i 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.Keywords
