Description
The luminescence properties of Tb3+-doped fluoride crystals under excitation with ionizing irradiation have been studied in order to assess the feasibility of using them as crystal detectors for in vivo radiotherapy dosimetry. In particular, it has been found that the radioluminescence intensity from both CsY2F7 and CsGd2F7 doped with 15 at% Tb3+ is almost six times that from the commercial Al2O3 : C detector. The spectral composition of emitted light has been analysed in order to determine the function of the Tb3+ activator ion during ionizing radiation-induced luminescence. The thermally stimulated luminescence of the crystals has also been investigated
