Rheology of chalcogenide glasses under light irradiation
Abstract
International audience ; Chalcogenide glasses undergo various photoinduced effects under light irradiation in their band-gap andsubband-gap range (refractive index, density, band-gap energy changes…). More specifically, the viscosityof these glasses can be tuned only by playing with the irradiation conditions, without any temperatureincrease. Because the photoinduced viscosity change (“photofluidity”) is athermal, it could allow glassforming at a micrometer scale (the size of a laser spot), and without risk of crystallization. Nevertheless, thephotofluidity is poorly understood up to now, especially because few methods exist to properly assess therheological properties under light irradiation. First because photoinduced changes occurs within time scalesshorter than the time required to measure viscoelastic properties by static methods (creep or relaxation tests).Secondly, because we can assume that the light is homogeneously absorbed (and thus, the mechanicalproperties homogeneously changed) along the thickness of the glass only if its dimensions are very thinregarding the light absorption coefficient. We proposed here a dynamical method to track the kinetic of thesechange in glass thin films under light cycles. We describe here this method and investigate the influence ofthe wavelength and the power of the light source on the viscoelastic properties. We analyze the kinetic of theevolution of these properties and the influence of the glass composition.
