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) ...
Kinetics and product distribution of p-nitrophenyl phosphate dianion solvolysis in ternary DMSO/alcohol/water mixtures are compatible with metaphosphate formation
(WILEY-BLACKWELLMALDEN, 2012)
The rate of solvolysis of p-nitrophenyl phosphate (PNPP) dianion in DMSO/water strongly decreases by increasing water concentration. Addition of linear alcohols (methanol, propanol, butanol, pentanol, and hexanol) at ...
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 ...
PARTICLES OF ALUMINUM METAPHOSPHATE CONTAINING CLOSED PORES - PREPARATION, CHARACTERIZATION AND OPTICAL-PROPERTIES

Spectroscopic investigations of OH- influence on near-infrared fluorescence quenching of Yb3+/Tm3+ co-doped sodium-metaphosphate glasses
(ELSEVIER SCIENCE BV, 2008)
Energy transfer processes were studied in two sets of Yb3+ and Tm3+ co-doped sodium-metaphosphate glasses, prepared in air and nitrogen atmospheres. Using Forster, Dexter, and Miyakawa theoretical models, the energy transfer ...
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 ...
Sodium distribution in mixed alkali K-Na metaphosphate glasses
(ROYAL SOC CHEMISTRY, 2010)
The local order and distribution of Na in the mixed alkali metaphosphate glasses K(x)Na(1-x)PO(3) were analyzed, with the aim to identify segregation or a random mixture of both cation species. X-Ray photoelectron spectroscopy ...
Cation size effects in mixed-ion metaphosphate glasses: structural characterization by multinuclear solid state NMR spectroscopy
(Royal Society of Chemistry - RSCCambridge, 2013-09)
Metaphosphate glasses with two monovalent species A1-xBxPO3 (0 <= x <= 1) show mixed-ion effects (MIE) in the dc conductivities and glass transition temperatures, which are strongly dependent on the cation size mismatch ...
