Short-wavelength emission analysis in Dy:ZBLAN glasses
چکیده انگلیسی
In this work we examine short-wavelength (blue, yellow and red) emission properties of dysprosium activated fluorozirconate ZBLAN glass. On the basis of the measured broad band absorption spectrum the intensity parameters Ωi were calculated using Judd-Ofelt formalism, yielding values of transition probabilities and radiative lifetimes. The basic spectroscopic characterization of Dy:ZBLAN was also performed, including visible emission and fluorescence decay measurements under pulsed, direct and two-photon up-conversion excitation. The theoretically predicted properties, specifically concerning the fluorescence lifetimes, were found to be in a rough agreement with experimentally determined values which was improved by isolation of magnetic dipole and impurity contributions to absorption spectrum.
