“…Mixed metal oxides with general formula A 2 B 2 O 7 ( A is a medium‐large cation and B is an octahedrally coordinated, high charge cation) have been widely studied for their potential applications. Here the A/B cations can be either in the +4/+3 or +5/+2 oxidation states . A 2 B 2 O 7 pyrochlore materials have attracted great interest due to their ability to form substituted and defective structures, allowing fascinating physical properties , .…”

Nanostructured Sr 2 As 2 O 7 samples were synthesized by hydrothermal crystal growth reactions between Sr(NO 3 ) 2 and As 2 O 3 with different stoichiometric Sr:As molar ratios as 1:1 (S 1 ), 1:2 (S 2 ), and 2:1 (S 3 ). The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and fourier-transform infrared (FT-IR) spectroscopy. Rietveld analysis showed that the obtained materials were crystallized well in the monoclinic crystal structure with the space group P2 1 . The morphologies of the synthesized materials were studied by field emission scanning electron microscopy (FESEM) technique. TEM images verified formation of the particles with nanometer size. Ultraviolet-visible spectra analysis showed that the synthe-* Dr. S. Khademinia 226S 2 was synthesized following a similar procedure as described for S 1 except 0.30 g (1.4 mmol) of Sr(NO 3 ) 2 ·5H 2 O and 0.28 g (1.4 mmol) of As 2 O 3 were used and the yield was 88 %. S 3 was also prepared similarly using 1.20 g (5.6 mmol) of Sr(NO 3 ) 2 ·5H 2 O and 0.29 g (1.4 mmol) of As 2 O 3 and the yield was 92 %.
