Indentation of glasses
2021, Progress in Materials ScienceCitation Excerpt :The mechanism of photosensitivity in the glasses used for optical fibers and the variation of it with UV exposure are rationalized by recourse to either the electronic models that rely on irradiation-induced defects affecting the electronic states, or the structural models that postulate changes to the intrinsic structure of the glass. The compaction–densification model, which belongs to the latter category, hypothesizes that the laser-irradiation induces compaction of the glass through internal structural rearrangements, and the resulting densification alters the index of refraction [107]. Aashia et al. [108] employed the nanoindentation technique to examine this, by studying germanosilicate preforms that were exposed to varying levels of UV irradiation.
Structural investigations of lead germanosilicate glasses doped with Nb<inf>2</inf>O<inf>5</inf> by means of spectroscopic and dielectric studies
2015, Journal of Molecular StructureCitation Excerpt :The exclusive scientific interest on these glasses, due to the close relationship exists between Ge and Si ions, is resulted to the series of significant differences and peculiarities rather than the conventional borosilicate and phosphosilicate glasses. The loss in transparency of these glasses when they were exposed to UV light leads to the enhancement of the defects in these glass matrix which make them photosensitive [6,7]. Currently, these glasses are being widely used for constructing CW Raman fiber lasers [8].
The structure of SiO<inf>2</inf>-GeO<inf>2</inf> glasses: A spectroscopic study
2008, Journal of Non-Crystalline SolidsCitation Excerpt :Germanosilicate glasses are used in a considerable range of applications in photonics, ranging from standard optical fibers for telecommunications to Bragg gratings or nonlinear optical devices [1]. The enhancement of defect production in GeO2-doped silica glass results in transparency loss and has led to the discovery of glass photosensitivity induced by UV exposure [2,3]. Vitreous germanates have also been proposed as materials for optical waveguides, due to their transmission characteristics in the infrared region.
