摘要：

Here is reported time-resolved up-converted luminescence of Er-3divided by-doped 70TeO(2)-30ZnO glasses. The photoluminescence shows non-exponential decay. This behaviour is explained as due to a multi-configurational distribution of luminescent ions in a disordered medium. Green and red up-converted fluorescences are obtained under cw laser excitation. Its dynamics, m lightly doped glasses, are mainly explained by an excited-state absorption (ESA) process. In heavily doped glasses, the time evolutions are explained in terms of ESA process within erbium ions and essentially of an energy transfer between excited ions. (C) 2004 Elsevier B.V.
