THERMOLUMINOPHORE Russian patent published in 2018 - IPC G01T1/11 

FIELD: physics.

SUBSTANCE: invention relates to the field of low-temperature thermoluminescence dosimetry of X-ray and gamma radiation. Thermoluminophore for low-temperature TSL dosimetry based on alon Al₅O₆N, synthesized from chemically pure α-Al₂O₃ and aluminum nitride containing a number of impurities, it has a composition in which the content of the basic substance Al₅O₆N – not less than 96 %; wherein in the original AlN the content of N₂ not less than 33.0 wt. %, O₂ – not more than 1.2 %, Fe – not more than 0.08–0.1 %, C – not more than 0.05 %, and the content of europium Eu²⁺ in the initial AlN and in the final alon product Al₅O₆N is 0.3–0.5 at. % (rel. Al).

EFFECT: determination of the dosage of elements and devices made on the basis of high-temperature superconductors operating in the fields of ionizing radiation at the temperature of liquid nitrogen, and also other devices operating at ultralow temperatures.
