Viscous flow changes induced by illumination in selected chalcogenide and phosphate glasses detected by thermomechanical analysis
2022, Journal of Non-Crystalline SolidsCitation Excerpt :Bulk As2S3 glass is material with a well-known two-dimensional layered structure consisting mainly of AsS3 trigonal pyramidal units where the individual layers are bound to each other by Van der Waals bonds [11,12]. In addition, As2S3 exhibits high photo-sensitivity (e.g. giant photo-expansion [13], photo-darkening [14] or even photo-viscous changes, e.g. [3,8]) and is extensively characterized from the point of view of thermal (e.g. glass transition temperature [15,16] and coefficient of thermal expansion [16]) and optical properties (e.g. the optical transparent window [17] or refractive index [18]). Phosphate glass (PbO)55(ZnO)10(P2O5)35 has also been studied by several authors.
Impact of composition and ex-situ laser irradiation on the structure and optical properties of As-S-based films synthesized by PECVD
2019, Optical MaterialsCitation Excerpt :The properties of the ChGS films can be modified by an external impact, for example, by laser irradiation or by heating/annealing in vacuum, in air or in an inert gas atmosphere. In the works [12–17] it was shown that As-S films demonstrate the ability to change their structural and optical properties under light exposure, for example: photo-darkening, photo-bleaching, photo-crystallization and other effects caused by rearrangements of the amorphous net. In addition, depending on the irradiation power, local heating thermal effects may also be observed.
Holographic grating preparation in Ag/As<inf>30</inf>S<inf>70</inf> multilayer and bilayer structures
2003, Journal of Non-Crystalline SolidsCitation Excerpt :Higher concentration of silver in light exposed areas compared to unexposed ones is a result of silver diffusion from unexposed parts [6], i.e. silver-doped regions in exposed areas of the grating are during grating formation conductively connected with the silver layer in unexposed part and elemental silver present there can provide a source of Ag+ ions. As a result silver source in unexposed area depletes, which has been previously reported by Tanaka and Hisakuni [10], Ong et al. [11] and by Wagner et al. [12]. The difference between photo-induced dissolution and photo-expansion is resolved by considering the process of surface dilatation, which was discussed in details in [6].
