Photodarkening profiles and kinetics in chalcogenide glasses

Very long physical ageing in inorganic polymers exemplified by the GexSe1−x vitreous system

“…A recent review of all these potential applications can be found in the proceedings of the international workshop on amorphous and nanostructured chalcogenides [2]. Among all these applications, we have well-known xerography, lithography [3], CD erasable disk [4], chemical sensor [5], long lengths of low-loss IR transmitting devices [6], switching and memory effects [7] and photo darkening [8,9]. The second one is linked to the relative easy achievement of the glassy state from the melt.…”

Elastic polyaniline with EPDM and dodecylbenzenesulfonic acid as plasticizers

“…We also employ Lambert's law which also presumes a local reaction, or negligible migrations of photogenerated carriers and absorption centres. These coupled differential equations can reproduce exposure‐time variations of the photodarkening, as experimentally demonstrated by Ducharme et al 14.…”

Characterization of As2(Se1−xSx)3 series glass system

“…In the past years, As 2 X 3 (X = S, Se) had ever been studied in the glassy type (short-range order) [2][3][4][5][6][7][8][9] as well as in their crystalline state [10][11][12]. As 2 Se 3 is a diamagnetic semiconductor that is crystallized in a layer-type structure of monoclinic symmetry (space group: P2 1 /n) [10,13].…”
