Modification of the MgO–Al2O3–TiO2–SiO2 Glass by Silver Diffusion for the Formation of Luminescent Molecular Clusters

The capabilities of diffusion treatment of alkali-free MgO–Al2O3–TiO2–SiO2 glass using Ag-containing salt melts or special pastes for the formation of luminescent molecular silver clusters in the glass surface layers have been demonstrated for the first time. This diffusion treatment also significantly increases the glass microhardness.
