  The results of the investigation of the spectral characteristics of new
luminescent substances based on rare-earth ions Eu3 + and Tb3 + in matrices of
double molybdates are presented in the article. The luminescence and excitation
spectra are considered, the decay times of the main transitions are determined,
and the color coordinates are determined. The results show the possible
suitability of using these compounds as white phosphor phosphor components.
