Excitation energy transfer between two 2i sites in triclinic L-EuBO3 and L-GdBO3 : EU3+

Abstract : Analysis of the excitation of Eu3+ ions in site A and site B in L-EuBO3 and L-GdBO3:Eu3+ at several temperatures have shown very efficient energy transfer and reciprocal processes between both sites. At 12 K, the transfer from site A to site B dominates the process and results in the fluorescence quenching of site A in L-EuBO3. At higher temperature, 77 and 300 K, the transfer and back transfer have nearly an equal rate and accordingly the same spectra from both sites are obtained despite of exciting site A or site B.
