Universidad de Zaragoza Directional solidification, thermo-mechanical and optical properties of (MgxCa1-x)3Al2Si3O12 glasses doped with Nd3+ ions 2015 Access copy available to the general public Unrestricted In this work glass rods of (MgxCa1-x)3Al2Si3O12 (x = 0, 0-5 and 1) doped with 1 wt% Nd2O3 were produced by the laser floating zone technique. Thermo-mechanical and spectroscopic properties have been evaluated. The three glass samples present good thermo-mechanical properties, with similar hardness, toughness and glass transition temperatures. The spectroscopic characterization shows spectral shifts in absorption and emission spectra. These spectral shifts together with Judd-Ofelt intensity parameters and ionic packing ratio have been used to investigate the local structure surrounding the Nd3+ ions and the covalency of the Nd-O bond. All obtained results agree and confirm the higher covalency of the Nd-O bond in the Ca3Al2Si3O12 glass. info:eu-repo/grantAgreement/EC/FP7/314630/EU/DEVELOPMENT OF NEW UV LASER FOR CUSTOMIZATION AT INDUSTRIAL LEVEL THROUGH HIGH QUALITY MARKING ON DIFFERNT MATERIALS/UV-Marking info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.148 2015 OPTICS 14 / 91 = 0.154 2015 Q1 T1 1.91 2015 Atomic and Molecular Physics, and Optics 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Conejos, D.
