Energy Transfer in Ce(0.85)Tb(0.15)F(3) Nanoparticles-CTAB Shell-Chlorin e(6) System

Formation and electronic excitation energy transfer process in the nanosystem consisting of Ce(0.85)Tb(0.15)F(3) nanoparticles, cetrimonium bromide (CTAB) surfactant, and chlorin e(6) photosensitizer were studied. It was shown that chlorin e(6) molecules bind to Ce(0.85)Tb(0.15)F(3) NP in the presen...

Sumario:Formation and electronic excitation energy transfer process in the nanosystem consisting of Ce(0.85)Tb(0.15)F(3) nanoparticles, cetrimonium bromide (CTAB) surfactant, and chlorin e(6) photosensitizer were studied. It was shown that chlorin e(6) molecules bind to Ce(0.85)Tb(0.15)F(3) NP in the presence of CTAB forming thus Ce(0.85)Tb(0.15)F(3) NP-CTAB-chlorin e(6) nanosystem. We consider that binding occurs via chlorin e(6) embedding in the shell of CTAB molecules, formed around NP. In the Ce(0.85)Tb(0.15)F(3) NP-CTAB-chlorin e(6) nanosystem, electronic excitation energy transfer from Ce(3+) to chlorin e(6) takes place both directly (with the 0.33 efficiency for 2 μM chlorin e(6)) and via Tb(3+).
