摘要：

The fluorescence decay of the F-4(3/2) transition in neodymium-doped silica optical fibers is analyzed with respect to neodymium concentration and temperature. New experimental data are compared with theoretical calculations based on (i) Grant's supposition [W.J.C. Grant, Phys. Rev. B 4 (1971) 648] and (ii) the Forster [T. Forster, Ann. Phys. (Puis)2 (1948) 55] and Dexter [D.L. Dexter, J. Chem. Phys. 21 (1953) 836] model. Grant's predictions are in reasonable agreement with the data. The nonexponential decay predicted by Forster and Dexter is insufficient to explain the experimental data. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
