Structure, luminescent, and scintillation properties of the obtained crystals have been studied. The presence of spatial inhomogeneities 1-3 µm size Lu2-xGdxSiO5:Ce has been shown due to fluctuations of Lu3+ і Gd3+ content in crystals, as well as nanosize inhomogeneities in the form of planes and columns formed at selective substitution of Lu3+/Gd3+ ions in LGSO:Ce, and Al3+/Ga3+ ions in YAGG:Ce in corresponding crystallographic sites. The common phenomenological approach to targeted obtaining of oxide scintillation crystals with improved light yield has been formulated, in particular, the tendency has been noted to the increase of light yield of solid solutions at substitution of atoms with the ionic radii ratio RА/RВ in the 1.07-1.15 range, the difference in bandgaps of solid solution components ΔEg>0.2 eV, the difference of electronegativities of substituted atoms >0.2.
