Neutrinoless double-beta decay is an important probe for the nature of neutrino mass and its absolute scale. Due to the luck of accuracy in calculations of nuclear matrix elements, measurements with different nuclei have to be done. Some of double-beta decay candidates, like Cd, Mo, and Ca could be introduced into the host lattice of scintillating crystals. Scintillation perfomance of CaMoO4 allow to measure neutrinoless double beta decay half life with the sensityvity of 5*10^25 years with reasonably compact detector. Optimization of crystal composition by substituting Pb or Zn for Ca may increase sensityvity to the level of 2-3*10^26 years. Prospects of molybdate scintillators in double-beta decay investigation are discussed.
