The detectors show an excellent energy resolution and ability of alpha signals rejection from gamma/beta signals. The radioactive contamination of the developed 100Mo enriched crystal scintillators is very low (232Th, 226Ra < 10 microBq/kg, 40K < 4 mBq/kg. The half-life of 100Mo relative to the 2n2b decay to the ground state of 100Ru is measured: Т1/2 = [6.90+-0.15(stat.)+-0.37(syst.)]x10^18 y. Li2MoO4-based scintillating bolometers have been chosen for the realization of a cryogenic 2beta experiment with 10kg of enriched 100Mo (CUPID-0/Mo) to prove the viability of this approach for CUPID. The first batch of twenty 0.2-kg Li2100MoO4 crystal scintillators has been produced to carry out a first phase of the experiment in the EDELWEISS-III set-up at Modane (France).
