Description	Sol-gel method has been successfully used for preparation of Ce-doped yttrium (YPS) and lutetium (LPS) pyrosilicates in powder form and of composite materials (REPS:Ce)0.1- (SiO2)0.9, RE=Y,Lu. XRD measurements showed that the crystallization of YPS take the place at 1100°C in the case of pure powder sample while, in the case of nanocomposites, it is shifted to the range of 1200-1300°C. Photo- and radioluminescence spectra of YPS:Ce and LPS:Ce crystallized nanophase in SiO2 host appeared very similar to their bulk single crystal analogs. Slightly shortened Ce3+ decay times in REPS:Ce/SiO2 can indicate the effect of small size of REPS:Ce nanospheres and different refractive index of surrounding medium. Rapid thermal treatment procedure indicates the possibility to obtain transparent bulk optical elements with scintillating REPS:Ce nanophase, but more experimental work has to be done to achieve good transparency and crack-free samples.
