Abstract
Optical absorption, fluorescence and photoacoustic spectra of Dy 3+ doped in oxyfluoroborate glass has been studied. Lifetime of 4F9/2 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+ + Dy 3+. © 2004 Elsevier B.V. All rights reserved.
