Paper Abstract

The experimental data for the nonradiative energy transfer from Nd3+ to Er3+ in Nd(1%), Er(15%) : YAG and in Nd(1%), Er(30%) : YAG is reanalyzed. The nonradiative energy transfer is not driven by a single multipolar interaction, but by a quadrupole-quadrupole and a dipole-dipole interaction. These interactions compete to each other, for Nd - Er neighbor pairs the quadrupole-quadrupole overcomes the dipole-dipole interaction, and for pairs at further distances the effect is reversed. The critical transfer distance parameter is constant, that is, 8.65 angstrom and does depend on neither the kind of interaction nor concentration. Our analysis is based on Monte Carlo simulations which place dopants into the 24c sites of the YAG lattice and calculate the Nd3+ and Er3+ emission transients.
