【 摘 要 】

The obtained results show that kinetics of light-assisted physical ageing in S-rich glasses can be well fitted with stretch-exponential Kohlrausch-type function, in which exponent values and the effective time relaxationconstant �? depend on the wavelength of incident photons. The obtainedvalues exhibit well-expressedminimum for the structural relaxation stimulated by light with energy of quanta comparable with the optical gap of the material. This effect is found to be similar to Se-rich glasses.
