| Abstract: | Erbium doped tin-silicate samples were prepared by sol-gel method. Optical absorption, infrared photoluminescence at 1.5 μm from 4I13/2-4I15/2 Er3+ electronic transition and data of refractive index change after exposure to 266 nm pulsed radiation were collected. The results show that Er-doped tin-silicate can be produced by the proposed sol-gel method with photosensitivity comparable to that of only tin-doped silica, showing refractive index changes up to 4×10−4. |
