Thermo and photochromic properties of Na2O-WO3-SbPO4 glasses
(Elsevier B.V., 2010-08-04)
Tungsten phosphoantimoniate-based glasses containing sodium oxide were prepared and their thermochromic and photochromic properties investigated. Thermochromism is achieved by annealing glass samples at a temperature above ...
Visible up-conversion and near-infrared luminescence of Er3+/Yb3+ co-doped SbPO4-GeO2 glasses
(2016-07-01)
Recent advances in glass chemistry have led to new multifunctional optical glasses of great technological importance. Glasses containing high amounts of antimony have been studied for use in nonlinear optics, near-infrared ...
Electrical conductivity of silicate glasses with tetravalent cations substituting Si
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
The effects of substituting Si by M4+ cations in soda-lime silica glasses were analyzed by impedance spectroscopy in the frequency range of 1 Hz-1 MHz. The glass composition was (mol%) 22Na(2)O center dot 8CaO center dot ...
