Thermoluminescence properties of LiMgF3 doped with Ce, Er and Dy.

The main dosimetric properties are reported of a new perovskite, LiMgF3, doped with Ce, Er and Dy impurities. An annealing temperature of 400 degrees C for one hour is necessary to erase any previous signal and to stabilise its sensitivity. A readout up to 450 degrees C gives the same result.

Thermoluminescent (TL) properties of the perovskite KMgF3 activated by Ce and Er impurities.

The perovskites are very interesting for their thermoluminescent properties and for their possible application as thermoluminescent dosimeters (TLD). In this paper we present results concerning the main dosimetric properties of KMgF3 activated by Ce and Er at various concentrations, i.e.
