Excitation and emission spectra. This shows excitation (*) and emission spectra of the neat polymer (2,7-NAF.DM, λ exc = 300 nm) and samples: 4* and 4 the silica with chemisorbed 2,7-NAF.DM; 5* and 5 carbon nanotubes mechanically mixed with the poly2,7-NAF.DM with the MWCNTs/polymer ratio 1:10; 6* and 6 carbon nanotubes with the poly2,7-NAF.DM chemisorbed via in situ grafted polymerization with the MWCNTs/polymer ratio 1:10 (spectra measured at λ exc of 450 nm and λ det of 550 nm); 7* carbon nanotubes with the poly2,7-NAF.DM chemisorbed via in situ grafted polymerization with the MWCNTs/polymer ratio 1:40 (spectra measured at λ exc of 450 or 300 nm)
