摘要: The formation of Ge nanoclusters in bulk and thin-film germanosilicate glass samples prepared by vapor deposition techniques then heat-treated molecular hydrogen at 800°C was studied Raman scattering optical spectroscopy. results demonstrate that the is accompanied a substantial increase concentration oxygen-deficient germanium centers OH groups. A mechanism nanocluster proposed. effects different process parameters on growth course preform fabrication fiber drawing are examined.
