Optical properties and frequency upconversion fluorescence in a Tm3+-doped alkali niobium tellurite glass
(American Institute of Physics (AIP), 2003-03-15)
Optical spectroscopic properties of Tm3+-doped 60TeO(2)-10GeO(2)-10K(2)O-10Li(2)O-10Nb(2)O(5) glass are reported. The absorption spectra were obtained and radiative parameters were determined using the Judd-Ofelt theory. ...
A polymeric europium complex with the ligand thiophene-2-carboxylic acid: Synthesis, structural and spectroscopic characterization
(2014-01-01)
A polymeric complex [Eu(α-tpc)3(α-Htpc) 2]n and its characterization by single crystal X-ray and thermal analysis, infrared and photoluminescence spectroscopies are described. The compound crystallizes in the monoclinic ...
Synthesis and Study of the Photophysical Properties of a New Eu3+ Complex with 3-Hydroxypicolinamide
(Springer/plenum Publishers, 2011-07-01)
This work reports on the synthesis and characterization of a new complex of Eu3+ with the 3-hydroxypicolinamide ligand (Hhpa). Here we present an approach for obtaining bis[2-carbamoyl(kappa O)pyridin-3-olato(kappa O')] ...
Raman scattering, differential scanning calorimetry and Nd3+ spectroscopy in alkali niobium tellurite glasses
(Elsevier B.V., 1999-05-01)
Alkali niobium tellurite glasses have been prepared and some of their properties measured by differential scanning calorimetry and Raman scattering. The vitreous domain was established in the pseudo ternary phases diagram ...
Dynamics of energy transfer and frequency upconversion in Tm3+ doped fluoroindate glass
(2004-09-01)
The spectroscopic properties of Tm3+-doped fluoroindate glasses (FIG) were described by single wavelength pumping in the red region. The Judd-Ofelt (J-O) theory was used to obtain the quantum efficiency of the 4f-4f ...
Spectroscopic properties of tellurite glasses co-doped with Er3+ and Yb3+
(2015-07-29)
Spectroscopic characterization of Er3+/Yb3+ co-doped tellurite glasses 70.8TeO2-5Al2O3-13K2O-(11-x)-BaO-0.2Er2O3-xYb2O3, where x=0, 0.4, 0.8, 1.2 and 2 mol% has been carried out through X-ray diffraction, Raman, absorption ...
