Different germanium dopant concentration and the thermoluminescence characteristics of flat Ge-doped optical fibres
Muhammad Safwan Ahmad Fadzil1, Ung, Ngie Min2, David Andrew Bradley3, Noramaliza Mohd Noor4.
The influence of elevated germanium concentration on the thermoluminesence characteristics of a novel
form of fabricated flat optical fibre was examined. All the samples were irradiated with two nominal
photon energies (6 MV and 10 MV) and 1.25 MeV gamma energy. Flat fibres with 10 mol % Ge
concentration provided the superior TL yield compared against that of 6 and 8 mol % Ge-doped optical
fibres for both 6 MV and 10 MV energy. Interpretation of the results has been aided by study of the glow
curves, revealing in particular new generation of defects in the flat fibres due to strain-generation at the
collapsed surfaces. The strain represent deep-energy defects.
