| Abstract: | Results of the investigation concerning thermoluminescence (TL) responses to X, gamma and neutron radiation fields for crystals of complex fluoride K2GdF5 undoped and doped with varying concentrations of Dy3+ ions are presented. Crystals doped with 5.0 at% Dy3+ have shown the most efficient TL response, with a linear response to doses for all the radiation fields. In the X rays range, the maximum TL response has been found to be 15 times more than the response for gamma. The fast and thermal neutron TL outputs were evaluated for K2Gd0.95Y0.05F5 and the contribution of the gamma component in the TL curve was estimated. |
