We investigated the silver photodiffusion kinetics into a chalcogenide layer by time-resolved neutron reflectivity measurements. To clarify the structural changes in the kinetics, we measure XAFS, neutron reflectivity, and Raman scattering of Ag/ Ge₂₀S₈₀ bi-layers exposed to the LED light with the peak wavelength at 405 nm with different exposure time.
