N2 - A large optically homogeneous LiRbMo3O10 single crystal was grown for the first time by the low temperature gradient Czochralski method. X-ray diffraction, elemental analysis, and differential thermal analysis confirmed the phase purity, high chemical purity, and thermal stability of the crystal; the onset of melting was determined to be 796 ± 1 K. For the grown single crystal, precise heat capacity data were obtained for the first time over the temperature range 5.7–330.7 K. No phase transitions were detected, the standard thermodynamic functions were calculated, and the limiting Debye temperature was determined as ΘD(0) = 292.7 ± 2.1 K. The crystal exhibits a band gap of Eg = 2.85 eV and broad red photoluminescence with an emission maximum at 728 nm (77 K). Analysis of steady-state and time-resolved photoluminescence showed that the thermal quenching is governed by a common thermally activated non-radiative relaxation pathway. The obtained results indicate that LiRbMo3O10 is a promising molybdenum-containing material for further investigation as a scintillating crystal for cryogenic bolometers.
