The TiO₂ nanoparticles were modified by phthalocyanine dinuclear sulphate (PDS). The results showed that a, the adsorption intensity of PDS in UV-Vis spectrum increased with increase in water content in [H₂O]/[Surft.] ratio; b, in AOT/isooctane reverse micelle system the UV-Vis spectral peak intensity for PDS decreased, broadened and redshifted with increase in concentration of TiO₂ in TiCl₄ solution, and the fluorescence spectral intensity for PDS decreased and then gradually to quenching also with increase in TiO₂ concentration.
