Application of standard and modified Judd-Ofelt theories to thulium doped fluoroindate glass
(Elsevier B.V., 1999-05-01)
Fluoroindate glasses of the following compositions: (40-x)InF3-20ZnF(2)-16BaF(2)-20SrF(2)-2GdF(3)-2NaF-xTmF(3) with x = 1,3 mol% were prepared in a dry box under an argon atmosphere. The absorption spectra at room temperature ...
Influence of crystal field potential on the spectroscopic parameters of SiO2.B2O3.PbO glass doped with Nd2O3
(ElsevierAmsterdam, 2011-05)
This paper presents the optical characteristics of Nd3+ silicate glass (SiO2-B2O3-PbO), synthesized by the fusion method. Two sets of samples were prepared: glass and corresponding glass ceramics. Optical absorption, ...
Orange emission in Pr3+-doped fluoroindate glasses
(2013-01-01)
We synthesize and study the properties of praseodymium doped fluoroindate glasses. Glass compositions with praseodymium molar concentrations up to 5% were obtained with good optical quality. Thermal, optical, and luminescence ...

Structural and spectroscopic properties of Eu3+ doped Y4Al2O9 compounds through a soft chemical process
(2018-12-01)
The present work reports on the synthesis, structural and optical properties of (Y1-xEux)4Al2O9 powders, with x ranging from 0.001 to 0.030. We prepared the materials using a modified polymeric precursors method, and the ...
Solid state photoluminescence studies of [EuLnH2(NO3)3](H2O)x macrocyclic complexes with Schiff base ligands
(Elsevier B.V., 2018)
Three EuIII macrocyclic complexes [EuLnH2(NO3)3](H2O)x based on the ligands derived from 2-hydroxy-5-methyl-1,3-benzenedicarbaldehyde and three different amines: o-phenylenediamine, Eu-OPDA; ethylenediamine, Eu-EDA; and ...
