Ceramic samples of tantalo-niobates solid solutions with yttrium and gadolinium cations (RE(NbxTa1-x)O4, RE = Y or Gd, and x=0÷1) have been obtained by solid-state synthesis. Luminescence properties of yttrium and gadolinium tantalo-niobates under X-ray and synchrotron radiation, UV and VUV radiation have been studied in visible and UV spectral regions. The luminescence mechanisms in yttrium and gadolinium tantalo-niobates have been determined as well.

Mg2+xSi0.7Sn0.3Sbm(0≤x≤0.2,m=0or 0.01) solid solutions have been successfully prepared by mechanical alloying and hot pressing as a solid-state synthesis route. All specimens were identified as phases with antifluorite structure and showed n-type conduction. The electrical conductivity of Mg-excess solid solutions was enhanced due to increased electron concentrations. The absolute values of the Seebeck coefficient varied substantially with Sb doping and excess Mg, which was attributed to the change in carrier concentration. The onset temperature of bipolar conduction was shifted higher with Sb doping and excess Mg. The lowest thermal conductivity of 1.3 W/mK was obtained for Mg2Si0.7Sn0.3Sb0.01. A maximumZTof 0.64 was achieved at 723 K for Mg2.2Si0.7Sn0.3Sb0.01.
