X-ray luminescence of ZnMoO4 crystals developed in the framework of the LUMINEU program

Luminescence of ZnMoO4 crystals developed in the framework of the LUMINEU double beta decay project under X-ray irradiation of different doses was studied in the temperature interval from 1.4 K to 295 K. We have found that concentration of shallow traps in ZnMoO4 crystals is much greater than the concentration of deep traps, and only shallow traps absorb a small part of the luminescence.
