Li₂B₄O₇ BASED TRANSPARENT TISSUE-EQUIVALENT RADIATION DETECTOR FOR THERMALLY OR OPTICALLY STIMULATED LUMINESCENCE DOSIMETRY AND FABRICATING METHOD THEREOF

摘要

There is provided a transparent tissue-equivalent radiation detector for thermally or optically stimulated luminescence dosimetry and a fabricating method thereof. Detector comprises a Li₂B₄O₇ base material, a dopant Mn, binding material silicon dioxide SiO₂, co-dopant which is selected from the group consisting of a divalent cation of either alkaline earth metal or transition metal with stable 2+ charge state, whereas said co-dopant does not reduce transparency of the detector in the region of wavelengths 320-750 nm. In fabricating the detectors the co-dopant is added to a pecursor together with lithium carbonate Li₂CO₃.
