| Abstract: | A heptamethine indocyanine dye with good water-solubility was synthesized and characterized in this paper.Spectral properties in different solvents and different concentrations of CTAB was measured,and it showed that the maximum of absorbance and emission(in ethanol) were 796nm and 813nm respectively.Fluorescence intensity of the dye became weak along with the increased viscosities of the solvents.Before the formation of micelles,with the increasing concentration of CTAB,the absorbance and fluorescence spec... |
