Nanocrystalline Eu³⁺-doped Mg2SiO4 powders were prepared with combined Pechini-solid phase synthesis. The structural properties were investigated with XRD, SEM and Raman spectroscopy. XRD pattern indicated that Mg₂SiO₄:Eu³⁺ were obtained with formation of other phase: MgO. Raman spectrum revealed good homogeneity and crystallinity of synthesized nanopowders. The luminescence properties were studied with measurement of excitation and emission spectra and decay curves. The effect of Eu³⁺ concentration on ⁵D₀ level lifetime was studied. Most probably, the observed shortening of ⁵D₀ level lifetime with Eu³⁺ concentration is caused by increase of nonradiative process probability.
