Crystallization of fluorindate and fluorogallate glasses
(1997-10-01)
Crystallization of binary InF3-MF2 and GaF3-MF2 (where M = Ba, Sr and Ca) glasses was studied. Characteristic temperatures and kinetic parameters E (activation energy) and n (Avrami exponent) were obtained. Stability against ...

EXAFS and Raman spectroscopy study of binary indium fluoride glasses
(1996-12-01)
Extended X-ray absorption fine spectroscopy (EXAFS) and Raman scattering studies of InF3-BaF2 and InF3-SrF2 binary glasses are reported. For all compositions, the local structure of the glasses is built with InF6 units. ...

Structural, thermal and optical properties of CaBO and CaLiBO glasses doped with Eu3+
(Elsevier B.V., 2014-09-01)
Thermal, structural and optical properties of undoped and Eu3+ doped CaBO and CaLiBO glasses were carried out by the Raman, FT-IR, UV-Vis absorption, fluorescence, thermoluminescence and DSC analyses. The addition of Li+ ...
Thermal and structural study of glasses in the binary system TeO2-Pb(PO3)(2)
(Elsevier B.V., 2013-11-01)
The main objective of this work has been to prepare and characterize the thermal and structural properties of glasses in the pseudo binary system TeO2-Pb(PO3)(2) with respect to the composition. Homogeneous and transparent ...
Structural studies on TeO2-PbO glasses
(Elsevier B.V., 2001-06-01)
Binary tellurite-based glasses in the TeO2-PbO system were prepared and its structure investigated by means of Raman Scattering and X-ray Absorption Spectroscopy. Both spectroscopies indicate strong modifications of the ...
