| Theeffect of freon heat treatment on optical properties of Er-doped silica glasses obtained by the sol-gel method was investigated. It was found that fluorine ions in the process of hydrolysis replace hydroxyl ions in the host and form the complexes with Er3+ ions. It leads to a significant improvement of optical properties of Er doped silica glass. |
