【 摘 要 】

Present work is dedicated to investigation of radiation optical properties of SiO2:Ge glass fibers produced by Fujikura and Corning Glass. Distribution of Ge dopant characteristics in core and cladding of quartz fibers have been determined. Ge dopant rings shaped luminescence in optical fibers has been observed. New method of determination the Ge dopant distribution in core and cladding cross sectional profile of silica glass fibers is presented. The thermoluminescence and light storage processes in fibers affected by x-ray radiation have been investigated. The photoluminescence investigations shows that there are two bands of luminescence with 400 nm and 550 nm maxima, which appear in different temperature stimulation conditions. Obtained results are discussed.
