Efficiency of Energy Transfer for TiO2 Nanoparticles with Fluorescein Dye

Abstract

For different amount of masses of TiO2 nanoparticles in dye solution, absorption and Fluorescence profiles of the suspension for TiO2 nanoparticles with Fluorescein (F) in distilled water solution, has been explored. An absorption spectra enhancement were detected for changed amount of masses, which specifies that the doping with TiO2 nanoparticles has a major effect on the dye absorption spectra. Contrarily, all fluorescence emission spectra for the dye, were quenched as TiO2 nanoparticles amount of masses increases because of Förster resonance energy transfer (FRET).
