Popis:	Spectral-luminescent properties of Eu2+ ions in alkaline earth dilithiosilicates of composition MLi2SiO4 (M = Ca, Sr, Ba) have been studied at 77 K. The reasons for the different positions of the Eu2+ 4f 65 d → 4f 7 emission band maximum in spectra of MLi2SiO4 were found based on the obtained results. It was shown that the increase in the decay time of the Eu2+ emission on going from CaLi2SiO4 (0.41μs) through BaLi2SiO4 (0.64 μs) to Sr-silicate (1.11μs) correlates with the shift of the emission maximum to longer wavelengths.
