Abstract The electronic spectra of Nile Blue acetate, phenoxazines, and its fluorinated analogs have been investigated experimentally and theoretically. The spectral-luminescence properties of these molecules have been studied in detail in ethanol and in nonpolar solvents (toluyl, dimethylsulfoxide) with an alcohol admixture (propanol, butanol, and isobutyl alcohol). The role of micelle formation in non-aqueous solvent on the spectral-luminescence of these molecules is elucidated. Also considered in this paper is the dependence of the quantum fluorescence yield of several oxazines and phenoxazines in ethanol on the structure of the dye molecules.
