Abstract

Copyright (c) 1997 Elsevier Science B.V. All rights reserved.Energy migration processes between Yb³⁺ ions have been investigated in BaY₂F₈ and YF₃ lattices. It has been found that energy transfer coefficient from Yb³⁺ to Tm³⁺ ions increases almost linearly with Yb³⁺ concentration at low Yb³⁺ concentrations and tends to saturate at higher Yb³⁺ concentrations. Comparison of the experimental results with calculated results, particularly on Monte Carlo simulation, has enabled to explain the above-mentioned results and to determine several parameters relevant to the migration processes.
