Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF:Yb
Michael F. Reid, Pubudu S. Senanayake, Jon-Paul R. Wells +5
We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF:Yb. The radically different radiative decay rates of the lowest exciton stat…
Extraction of crystal-field parameters for lanthanide ions from quantum-chemical calculations
L. Hu, M. F. Reid, C. K. Duan +2
A simple method for constructing effective Hamiltonians for the 4fN and 4fN-15d energy levels of lanthanide ions in crystals from quantum-chemical calculations is presented. The me…
Spectroscopy of high-energy states of lanthanide ions
Michael F. Reid, Liusen Hu, Sebastian Frank +3
We discuss recent progress and future prospects for the analysis of the 4f5d excited states of lanthanide ions in host materials. Ab-initio calculations for Ce in LiY…
The unusual temperature dependence of the Eu fluorescence lifetime in CaF crystals
C. K. Duan, A. Mejerink, R. J. Reeves +1
Fluorescence lifetimes of Eu doped in CaF are measured at various temperatures between 4K and 450K. The lifetime increases with between 100K and 300K, in contrast to the…
A simple model for transition of heavy lanthanide and actinide ions in crystals
Chang-Kui Duan, Michael F. Reid, Gang Ruan
The transition model by Duan and co-workers [Phys. Rev. B {\bf 66}, 155108 (2002); J. Solid State Chem. {\bf 171}, 299 (2003)] has been very useful in interpreting the $f\…
General calculation of transition rates for rare-earth ions using many-body perturbation theory
Chang-Kui Duan, Michael F. Reid
The transition rates for rare-earth ions in crystals can be calculated with an effective transition operator acting between model and states calculated…
