Abstract

-doped fluorozirconate(ZBLAN)glasses were prepared

and the absorption and emission spectrum of Dy

ions in ZBLAN glasses were measured.Using Judd-Ofelt theory

parameters of Dy

ions in fluorozirconate glasses according to the absorption spectrum and the emission cross of

tranbsition of 1.3μm emission were calculated Ω

.The calculated results showed that ZBLAB glass is a good host for Dy

ion doped

and higher emission cross of Dy

than Pr

:ZBLAB give a good promising for Dy

as the doped ion in 1-3μm fiber amplifier.The effect of the Dy

concentration on the emissiion intensities has been discussed

emission intensities of Dy

ions become stronger with incresaing the doping concentration.Concentration quenching will occur when concentration of Dy

exceeds 1.5mol%.
