Abstract
This work is devoted to experimental study of a few technological approaches allowing improving thermoluminescence efficiency of Mn2+ ions in the Czochralski-grown YAlO3:Mn crystals applicable for thermoluminescent (TL) dosimetry of ionizing radiation. These approaches include changes of the crystal stoichiometry (Y2O3-Al2O3 ratio), the form of manganese doping (MnO2 or MnO) and the after-growth high-temperature thermal treatments of the crystals in oxidizing and reducing atmosphere. It is shown that these measures allow to increase the TL efficiency of Mn2+ ions in the YAlO3:Mn crystals several tens of times.
