Assessment of Ge-doped optical fibres subjected to x-ray irradiation
We have reported the thermoluminescence (TL) response of five different diameters ~120, 241, 362, 483, and 604 μm of 6 mol percent Ge-doped optical fibres. The perfomance of the Ge-doped optical fibre are compared with commercially available TLD-100 chips (LiF:Mg,Ti) in terms of their sensitivity and minimum detectable dose (MDD). The irradiation was performed using X-ray machine (Model ISO ‘Na...
متن کاملEvolution of photo-induced defects in Ge-doped fiber/preform: influence of the drawing.
We have studied the generation mechanisms of two different radiation-induced point defects, the Ge(1) and Ge(2) centers, in a germanosilicate fiber and in its original preform. The samples have been investigated before and after X-ray irradiation using the confocal microscopy luminescence and the electron paramagnetic resonance techniques. Our experimental results show the higher radiation sens...

متن کاملPlasmonic Ge-doped ZnO nanocrystals.
We present the first colloidal synthesis of Ge-doped ZnO nanocrystals, which are produced by a scalable method that uses only air and moisture stable precursors. The incorporation of tetravalent Ge ions within ZnO nanocrystals generates a surface plasmon resonance in the near-mid infrared, and induces a change in morphology, from isotropic spheroidal nanocrystals to rod-like, elongated structur...
متن کاملDispersion and refractive index measurement for Ge, B-Ge doped and photonic crystal fibre following irradiation at MGy levels
We have investigated the effects of ionizing radiation-induced changes on dispersion and refractive index in photonic crystal fibre, boron co-doped photosensitive fibre and standard SMF-28 fibre up to a level of 7 MGy of 60Co γ -radiation. We have been unable to observe any changes within an experimental error of ∼1% for the dispersion value and <1.5 × 10−3 for the refractive index.
