Thermal Behaviour Of Silver In Ion-Exchanged Soda-Lime Glasses

The refractive index and the nonlinear optical properties of sodium silicate glass can be easily tailored by replacing the sodium with silver. However, the thermal responses of silver and the corresponding modifications of the silica network in ion-exchanged glass under heating are still not clear. X-ray photoelectron spectroscopy has been used to study the in-situ behaviour of silver and Si02 networks on the surfaces of silver-ion-exchanged-content soda-lime glasses during heating and cooling processes under ultra high vacuum. Temperature-dependent concentration changes and oxidation states have been monitored.
