Defect-induced photoluminescence of powdered silica glass
(2008-03-27)
Visible photoluminescence was generated in standard soda-lime-silica glass powder, mechanically milled in a high-energy attrition mill. The broad emission band maximum shows a linear dependence on the exciting wavelength, ...
Urbach energy parameter of flash evaporated amorphous gallium arsenide films
(2002-04-01)
The dependence of the optical absorption edge on the deposition crucible temperature is used to investigate the electronic states in As-rich a-GaAs flash evaporated films. The Urbach energy parameter, determined from ...
Kinetics of martensitic phase decomposition in the Cu-10wt.%Al alloy with Ag additions
(2008-11-24)
The study of the kinetics of martensitic phase decomposition in the Cu-10wt.%Al alloy with Ag additions showed that the presence of Ag retarded the eutectoid decomposition reaction and enhanced martensite stabilization. ...
Mechanical damping of the snoek peak in tantalum - Oxygen system
(2008-03-27)
Interstitial solutes in body-centered cubic metals, such as oxygen in tantalum, produce ideally Snoek effects when they are in solutions enough diluted. However, for higher concentration of these solutes, more complex ...

TL and EPR properties of apophyllite dependents on point defects.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
Apophyllite of chemical formula (KCa)Ca4Si8O20(F,OH)8H2O is a mineral that belongs to the
family of sheet silicates. In its crystal structure, tetrahedra SiO4 are arranged in four-fold and
eight-fold rings, and alternate ...
