In this work, we investigate visible emission properties of dysprosium-doped yttrium aluminum garnet (YAG) waveguides prepared by the liquid phase epitaxy (LPE) method, which allowed obtaining samples of activator concentrations ranging from 0.2at% up to ca. 18at%. This unique set of Dy:YAG/YAG waveguides has been carefully examined by means of highly resolved laser spectroscopy to explore the luminescence...
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 Ω i were calculated using Judd–Ofelt formalism, yielding values of transition probabilities and radiative lifetimes. The basic spectroscopic characterization of Dy:ZBLAN...
In the paper, we investigate on the visible emission of highly doped Dy:YAG/YAG planar waveguides. The disposed set of unique samples has been prepared by the liquid phase epitaxy (LPE) method. The concentration-dependent absorption and emission spectra as well as fluorescence dynamics profiles have been recorded under direct and up-conversion excitation giving a starting point for further considerations...
