Resonance Raman spectra of S@SWCNTs in comparison with empty SWCNTs, measured with 785 nm (a) and 532 nm (b) laser excitations. Raman spectra of empty DWCNTs and S@DWCNTs, measured with 785 nm (c) and 532 nm (d) laser excitations. The asymmetric BWF lines associated with metallic CNTs or enhanced in presence of metallic 1D sulphur chains are highlighted by the arrows in a and d. Met, metallic CNT; Semi, semiconducting CNT.
