Electron Properties of Nanocomposites of the Squaraine Dyes with SWNTs and MWCNTs: Optical Spectroscopy and Modelling

467–476 (2025)

PACS numbers: 71.20.Tx, 73.20.Hb, 73.22.-f, 78.20.Bh, 78.66.Tr, 78.67.Sc, 81.05.ub

The optical properties of nanocomposite films based on dyes with single- and multiwalled nanotubes are considered. As shown, depending on the type of nanotubes, there is a transformation of the absorption spectra compared to the spectra of the dye films on quartz substrates. Model of the complexes based on C70 fullerene with squaraine dyes is used to demonstrate the possibility of dependence of the absorption spectra on the diameter of the carbon structure.

KEY WORDS: single-walled carbon nanotubes, multiwalled carbon nanotubes, C70 fullerenes, squaraine dyes, films, optical spectroscopy, quantum-chemical calculations
