Abstract
Er-doped silica glasses (5000ppm Er/Si mol) were prepared by sol-gel method. Gel samples underwent dehydration in carbon tetrachloride environment. It shows that carbon tetrachloride can remove hydroxyl groups effectively. As a result, I13/2-I15/2 fluorescence lifetime rises considerably. It is also found that fluorescence lifetime is strongly dependent on OH concentration. For samples annealed in carbon tetrachloride at 900°C, fluorescence lifetime as long as 6ms was reached.
