摘要：

Optical absorption, fluorescence and photoacoustic spectra of Dy3+ doped in oxyfluoroborate glass has been studied. Lifetime of F-4(9/2) level has been measured for different concentration of Dy3+. Effect of concentration quenching on the lifetime and the fluorescence yield has been observed and the mechanism of energy transfer discussed. The energy transfer from Pr3+ to Dy3+ has been observed and explained in a codoped glass containing Pr3+ + Dy3+. (C) 2004 Elsevier B.V. All rights reserved.
