L. Smentek et Ba. Hess, Theory of host sensitized luminescence of rare earth doped materials. I. Parity considerations, J ALLOY COM, 300, 2000, pp. 165-173
The theory of host sensitized luminescence based on the electrostatic model
of interaction is extended beyond the free ionic system approximation and
improved by the contributions that break the limitations of the single conf
iguration approximation. The approach is based on double perturbation theor
y and defined in the terms of tensor operators. The parity requirements and
consequent selection rules are discussed in the case of various contributi
ons to the energy transfer probability defined up to the third order of per
turbation expansion. (C) 2000 Elsevier Science S.A. All rights reserved.
