The role of the Eu3+ ions in structure and photoluminescence properties of SrBi2Nb2O9 powders
(Elsevier B.V., 2009-04-01)
This work rationalized for the first time the key role of Eu3+ ion in the doping process of SrBi2Nb2O9 (SBN) compound. This process allows LIS to understand the role of Eu3+ as lattice modifier as well as to obtain information ...
Microwave synthesis of YAG : Eu by sol-gel methodology
(Elsevier B.V., 2007-10-01)
Yttrium-aluminum oxides are interesting compounds and they have been extensively used as host for lasers and phosphors, due to their stable physical and chemical properties. The fabrication of yttrium-aluminum garnet (YAG) ...
Towards an insight on the photoluminescence of disordered CaWO4 from a joint experimental and theoretical analysis
(Elsevier B.V., 2005-04-01)
A joint experimental and theoretical study has been carried out to rationalize for the first time the photoluminescence (PL) properties of disordered CaWO4 (CWO) thin films. From the experimental side, thin films of CWO ...
