Effect of Manganese Concentration on Thermoluminescent Properties of $YAlO_{3}:Mn$ Crystals

This work is devoted to experimental study of the effect of manganese concentration on thermoluminescent properties of $YAlO_{3}:Mn$ crystals grown by the Czochralski method. A new type of emitting centers beside of $Mn^{4+}$ and $Mn^{2+}$ ions was revealed at low concentration of manganese ions in the crystal. These centers are responsible for the high-temperature thermoluminescent peak at 570 K. A potential of this thermoluminescent peak for thermoluminescence dosimetry application is discussed.
