文摘

The red-ox states of cerium have been investigated in a photo-thermo-refractive glass. During the exposure to UV light Ce3+ is oxidized to Ce4+. Heat treatment results in the reverse effect. Metallic silver clusters are only formed in tin/antimony codoped samples. Formation of silver clusters is more efficient in the formerly reduced glasses.
