Abstract

The results of an analysis of the energy transfer and two‐step excitation in LaF₃:Yb,Er are presented. The physical model assumes that the Yb³⁺ and Er³⁺ ions are tightly coupled and transfer occurs both ways. The simple model used is able to explain the experimentally observed time dependence and radiant efficiency provided one assumes the following decay times: Yb³⁺(⁵F_5/2), 2 msec; Er³⁺(⁴F_7/2), ∼1 μsec; Er³⁺(⁴S_3/2), 0.125 msec.
