Özet
Sodium lanthanides double tungstates NaRE(WO4)2 (RE = Pr, Ho, Sm) were synthesized by solid-state reactions at 800 °C for 10 h by using sodium carbonate (Na2CO3), tungsten trioxide (WO3), lanthanides oxide (RE2O3) as raw materials at stoichiometric 1:1:2 Na:RE: W molar ratio. The synthesized materials were characterized by powder X-ray diffraction (PXRD) and field emission scanning electron microscopy (FESEM) technique. Rietveld analyses indicated that the NaHo(WO4)2 and NaSm(WO4)2 crystallized in the tetragonal crystal system with the I41/a space group and NaPr(WO4)2 was crystallized in the monoclinic crystal system with the P2/n space group. The FESEM images illustrated that the morphology of the patterns had homogeneous sponge structures. The energy band gaps were calculated by using diffuse reflectance spectroscopy (DRS). Also, the electrical behavior of them was studied in detail, and vibrating sample magnetometer (VSM) plot of the NaRE(WO4)2 (RE = Pr, Ho, Sm) possesses paramagnetic behavior. Finally, the anticancer character of products on HepG2 cells line was investigated.
