Deactivation of the photoionization excitation mechanism of rare-earth intraion emission in ZnS

Krzysztof Swiatek, M. Godlewski

A new, very efficient excitation mechanism of the rare-earth (RE) intraion emission was observed recently. This is a process in which the RE ion undergoes ionization and the RE intraion emission is induced when the ionized carrier is recaptured by the RE. The capture process proceeds via an intermediate state due to RE bound exciton (BE), from which the energy is transferred to the RE excited state. In this letter we discuss mechanisms which limit the efficiency of this excitation channel. The first is the thermal dissociation of the RE BE, which reduces the efficiency of the energy transfer thus quenches the RE intraion emission. It is also indicated that an efficient energy transfer from RE Be to iron Fe2+ centers competes with the transfer of the BE energy to RE core states. Our results mean that the practical utilization of the above excitation mechanism of emission in the RE-activated ZnS devices may be hampered by the common contamination of this material with iron.

Strain-mediated ion–ion interaction in rare-earth-doped solids

Anne Louchet-Chauvet, T. Chanelière

It was recently shown that the optical excitation of rare-earth ions produces a local change of the host matrix shape, attributed to a change of the rare-earth ion's electronic orbital geometry. In this work we investigate the consequences of this piezo-orbital backaction and show from a macroscopic model how it yields a disregarded ion-ion interaction mediated by mechanical strain. This interaction scales as1/r3, similarly to the other archetypal ion-ion interactions, namely electric and magnetic dipole-dipole interactions. We quantitatively assess and compare the magnitude of these three interactions from the angle of the instantaneous spectral diffusion mechanism, and re-examine the scientific literature in a range of rare-earth doped systems in the light of this generally underestimated contribution.
