Energy transfer and migration processes in Yb3+-ion-sensitized, rare-earth-ion-activated luminescent materials

Rare earth fluorescent complexes monomer with activated double bonds was synthesized by using Eu as the central atom, Methacrylic acid and 1, 10-Phenanthroline monohydrate as ligand. The structure of resultant Eu (MAA)3Phen was determined by infrared spectrum, ultraviolet spectrum and element analysis, and the fluorescence property of the complexes was tested by fluorescence spectra and fluorescence microscopy. Compared with conventional luminescent materials, this resultant complexes show greater fluorescence intensity. The analysis has revealed that with the increase of rare earth ion concentration from 4×10-5mol·L-1 to 4×10-3mol·L-1, the fluorescence quenching phenomenon appeared in the complexes solution.

Pl Spectra

Enhancement of emission intensity of rare-earth-ion doped SrTiO 3 by Al addition has been investigated. In the case of Pr 3+ and Tb 3+, addition of 23-mol% Al intensifies emission by more than 200 times. In contrast, the addition of 20 mol% Al intensifies emission at most by three times in the case of other rare-earth ions. The temperature dependence of PL spectra shows that the energy transfer from carriers to Pr 3+ or Tb 3+ ions is much more efficient than that to other rare-earth ions in SrTiO 3. It can be speculated that the energy transfer in SrTiO 3: Pr 3 or Tb 3+ occurs from carriers to Pr 3+ or Tb 3+ ion via 4f-5d transitions, which are much higher in oscillator strength than 4f-4f transitions.
