|Title:||Spectroscopic study of calcium aluminate-based glasses with Nd3+.|
|Abstract:||Multicomponent ( Al2O3, CaO, SiO2, MgO) calcium aluminate-based glasses containing Nd3+ were prepared in order to evaluate their possibilities as laser host materials. The refractive index, UV-visible-near IR absorption spectrum, IR and visible luminescence spectra, and fluorescence decay time were measured. Judd-Ofelt model was used to obtain experimental intensity parameters (Omega(2), Omega(4) and Omega(6)), emission cross-section, radiative lifetimes, emission branching ratios and quantum efficiency.|
