Thermoluminescence of aluminophosphate glasses in the metaphosphate composition
(Elsevier B.V., 2006-05-01)
Potassium aluminum phosphate (KAP) glasses in the system xKPO(3)-(100-x)AI(PO3)3 with x = 10, 30 and 50 mol% were prepared in the metaphosphate composition. The glasses were doped with MnO2 and their thermoluminescent (TL) ...
Anelastic spectroscopy in potassium aluminum metaphosphate glasses
(2006-09-15)
Anelastic spectroscopy (internal friction and the dynamic modulus) was measured by means of a torsion pendulum at 3-12 Hz, in the range of 100-300 K, for a KAP metaphosphate glass. Two thermally activated internal friction ...

Spectroscopic study and local coordination of polyphosphate colloidal systems
(Amer Chemical Soc, 2005-03-01)
The interaction between metaphosphate chains and the metal ions Ca2+ and Eu3+ has been studied in water by Eu3+ luminescence, infrared absorption, and P-31 NMR spectroscopy. Two main families of sites could be identified ...
Scandium fluorophosphate glasses: a structural approach
(Elsevier B.V., 2002-12-01)
A systematic investigation on glass formation in the ternary system InF3-BaF2-[Sc(PO3)(3)](n) has been carried out. Scandium polyphosphate [Sc(PO3)(3)](n) has been used as a third component in order to investigate the ...
Enhanced Eu3+ Emission in Aqueous Phosphotungstate Colloidal Systems: Stabilization of Polyoxometalate Nanostructures
(Amer Chemical Soc, 2010-09-07)
Luminescent Eu3+-containing polyphosphate tungstate aqueous colloidal systems were prgared and studied as a function of the relative polyphosphate tungstate content. In polyphosphate-rich solutions, Eu-H- ions occupy ...
Er(3+) doped phosphoniobate glasses and planar waveguides: structural and optical properties
(Iop Publishing Ltd, 2008-07-16)
Phosphoniobate glasses with composition (mol%) (100-x) NaPO(3)-xNb(2)O(5) ( x varying from 11 to 33) were prepared and characterized by means of thermal analysis, Fourier transform infrared spectroscopy, Raman scattering ...
