Effect of mixed alkali ions on the structural and spectroscopic properties of Nd3+ doped silicate glasses
(ElsevierNL, 2024)
In the present work the effect of alkali ions (Li, Na, K) and the combination of them on structural and spectroscopic properties of Nd3+ doped silicate glasses were systematically investigated. Results from infrared and ...
High pressure effect in the near-infrared emission of Nd3+-doped alkali silicate glasses
(Taylor & FrancisGB, 2022)
The effect of high pressure (7.7 GPa) densification on the absorption and near-infrared emission of Nd-doped lithium, sodium and potassium disilicate glasses was investigated. Judd-Ofelt parameters O¿ (¿ = 2, 4 and 6) were ...
Síntese e caracterização de sabões metálicos de lantanídeos (III)
(Universidade Estadual Paulista (Unesp), 2015-10-09)
The present study describes synthesis of Eu3+, Nd3+, Dy3+, Tb3+ and Yb3+ behenates using a simple metodology resulting on high purity products. The compounds were analyzed using IR-Spectroscopy, TG-DTG, DSC, %C, %H, XRD, ...
