摘要

A study of energy transfer was performed in dysprosium-terbium-doped silicate glasses at room temperature. Enhancement of the Tb3+ emission and a decrease in the Dy3+ emission are observed as a result of energy transfer from Dy3+ ions to Tb3+ ions. The energy transfer efficiencies, transfer probabilities, as well as average donor-acceptor distances were also calculated. It is concluded that the energy transfer mechanism between Dy3+ and Tb3+ ion is mainly electric dipole-dipole in nature. (C) 2008 Elsevier B.V. All rights reserved.
