摘要：

Absorption and emission as well as emission decay times of Ho3+ ions embedded in LaAlO3 single crystal were measured. The experimental results were analysed in the frame of the Judd-Ofelt theory. Energy levels, oscillator strengths and probabilities of radiative transitions were determined. The results indicate on nonradiative transitions due to cross-relaxation down and up-conversions processes. (C) 2004 Elsevier B.V. All rights reserved.
