In this study, Yb_1.98Lu_0.02Sn₂O₇ and Yb_1.90Eu_0.10Sn₂O₇ were produced by solid state reaction method. The characterization of the samples was achieved by thermal analysis (TG/DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM-EDX), photoluminescence spectrophotometer (PL), LCR-meter and d_33-m. Thermal behaviours, crystal structures, surface morphology, elemental analysis, photoluminescence properties, deielectric and piezoelectric properties and Curie temperature of Yb_1.98Lu_0.02Sn₂O₇ and Yb_1.90Eu_0.10Sn₂O₇ were investigated. X-ray diffraction datas indicate that the formation of cubic crystal structures were achieved for both materials. The photoluminescence and electrical measurements showed that Yb_1.98Lu_0.02Sn₂O₇ and Yb_1.90Eu_0.10Sn₂O₇ have both luminescent and piezoelectric properties.
