Effects of the particle size and nucleation temperature on tellurite 20Li(2)O-80TeO(2) glass crystallization
(Elsevier B.V., 2006-10-25)
20Li(2)O-80TeMO(2) glasses were heat annealed at different temperatures between T-g and T-x and studied by using XRD, FTIR spectroscopy and DSC techniques to understand the crystallization kinetics in this glass matrix. ...
Thermally stimulated crystallization glass system of (20-x)LiO2-80TeO(2)-xWO(3)
(Academic Press Inc. Elsevier B.V., 2011-05-01)
Tellurite glasses of the (20-x)LiO2-80TeO(2)-xWO(3) system were synthesized (x=0, 5, and 10) and annealed at different temperatures, and the crystallization kinetics was studied using XRD. FTIR spectroscopy, and DSC ...
Inversion in the temperature coefficient of the optical path length close to the glass transition temperature in tellurite glasses
(American Institute of Physics (AIP), 2009-06-22)
In this study, thermal lens spectrometry was applied to determine the thermo-optical properties of fragile tellurite glasses as a function of temperature, close to the glass transition region. The results showed an inversion ...
Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
(2013-09-20)
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...
Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...
Tellurium in organic synthesis: the enantioselective synthesis of the pheromone blend components of Mayetiola destructor, Drosophila mulleri and Contarinia pisi
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The components of the pheromone blend of Mayetiola destructor, Drosophila mulleri, and Contarinia pisi were synthesized in high enantiomeric excess (99% ee) from a common enantiopure dianion prepared from an enantiopure ...
Near-infrared nonlinearity of a multicomponent tellurium oxide glass at 800 and 1,064 nm
(Springer, 2014-07-01)
We report on the nonlinear (NL) optical properties of glassy TeO2-GeO2-K2O-Bi2O3 at lambda = 800 nm and lambda = 1,064 nm. Using the Kerr gate technique with a laser delivering 150 fs pulses at 800 nm, we demonstrated the ...
Surface-plasmon-enhanced frequency upconversion in Pr(3+) doped tellurium-oxide glasses containing silver nanoparticles
(American Institute of Physics (AIP), 2008-05-01)
A frequency upconversion process in Pr(3+) doped TeO(2)-ZnO glasses containing silver nanoparticles is studied under excitation with a nanosecond laser operating at 590 nm, in resonance with the (3)H(4)-->(1)D(2) transition. ...
Performance of ZnSe(Te) as fiberoptic dosimetry detector
(Pergamon-Elsevier Science Ltd, 2016-10)
Fiberoptic dosimetry (FOD) is an experimental technique suitable for in-vivo, real time dosimetry in radiotherapy treatments. FOD relies on using a small scintillator coupled to one end of a long optical fiber. The ...
Synthesis, crystal structure and theoretical studies of aryltellurenyl tetramethylthiourea(tmtu) iodine complexes: Ph-Te(tmtu)I (1) and beta-naphtyl-Te(tmtu)I (2)
