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.
