Abstract :
Rare earth complexes/silver nanoparticles nanocomposite was prepared by introducing Tb(TTA)3Bipy as stabilizer. The radiative properties of the nanocomposite were studied by experiments and spectra calculation. The transmission electron microscope image of the composite indicates that the silver nanoparticles are spherical, monodispersed and with an average size of 18 nm. Fluorescence study shows silver nanoparticles have both enhancement effect and quenching effect on the fluorescence of europium complex, the total effect in such a composite system is an enhancement effect. Theory calculation prognosticates that the newly synthesized rare earth complexes/silver nanoparticles nanocomposite could be used in polymer optical fiber amplifier and laser materials.
