Fluorescence emission of phenosafranin dye was quenched when this dye was adsorbed on Ti02 particles. Diffuse reflectance laser flash photolysis measurements have shown transient absorption corresponding to the cation radical of phenosafranin when the dye adsorbed on TiOr, was excited with a 532 nm
