Abstract: The specific features of the crystal structure of crystal phosphors Y$_3$Al$_5$O$_{12}$ : Ce$^{3+}$/Lu$_2$O$_3$/(Lu$_2$O$_3$ : Ce) synthesized by the colloidal chemical method have been investigated by neutron diffraction at room temperature. The influence of the method used for introducing Lu$_2$O$_3$ into the system on the structure and luminescence properties of the samples has been analyzed. The investigation has revealed that the spectra of the samples prepared under the most nonequilibrium conditions are characterized by the Stokes shift and high photoluminescence intensity. This has been explained by the disorder of their crystal structure due to the formation of stable associates of defects.
