Spectroscopic Study Of Calcium Aluminate-based Glasses With Nd3+ [estudo Espectroscópico De Vidros A Base De Aluminato De Cálcio Contendo Nd3+]

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 (Ω2, Ω4 and Ω6), emission cross-section, radiative lifetimes, emission branching ratios and quantum efficiency.232161166Hafner, H.C., Kreidl, N.J., Weidel, R.A., (1958) J.
