Abstract

Lithium magnesium molybdate (Li2Mg2(MoO4)3) crystals were grown by the low-thermal-gradient Czochralski method. Luminescence properties of the material (emission spectra, thermally stimulated luminescence, dependence of intensity on temperature, phosphorescence) have been studied under X-ray excitation in the temperature interval from 8 to 400 K, while at the same being operated as a scintillating bolometer at 20 mK for the first time. We demonstrated that Li2Mg2(MoO4)3 crystals are a potentially promising detector material to search for neutrinoless double beta decay of 100Mo.
