a Schematic illustration of the fabrication of fluorescent dots. b The normalized absorption and c the normalized PL spectra of the four kinds of AIE dots dispersed in water. d The normalized fluorescence images of tubes containing the aqueous dispersion of four fluorescent dots with the same concentration and the normalized cross-sectional fluorescence intensity profiles along the green lines. (1) 2TT-oCB dots; (2) 2MTT-oCB dots; (3) 2MPT-oCB dots; (4) 2FT-oCB dots. e The plots for the integrated fluorescence intensities of 2FT-oCB dots in heavy water and IR-26 in the 1, 2-dichloroethane at five different concentrations. a.u. here represents arbitrary units. f The DLS results of the 2FT-oCB dots. g The photostability test of the 2FT-oCB dots under continuous irradiation.
