Assessment of Ge-doped optical fibres as a TSL-mode detector

This study analyses the thermally stimulated luminescence (TSL) or thermoluminescence glow curve between 300 and 773 K of germanium-doped silica optical fibre and finds a main glow peak at around 500 K with a characteristic spectral emission centred at 400 nm. Both features are particularly suitable for dosimetry. Thus, an investigation by the TSL technique of some first clinically relevant features of a TSL sensor like the doseand dose rate-responses is obtained. The presented studies show that germanium doped silica fibres have potential dosimetric properties and should be excellent TSL-mode detectors in instances of radiotherapy (clinical dosimetry) and in-vivo radiation dosimetry as well in the field of nuclear facilities.
