خلاصه مقاله:
Pyrochlore-type oxides are adopted by many binary metal elements having the general formula A2B2O7 where A is a 2+ or 3+ ion and B is a 5+ or 4+ ion [1]and crystallize in the cubic space group Fd3m. The pyrochlore phase is stable up to rA: rB =1.8 and beyond this value the fluorite structure becomes more favorable [2]. The exact formula for this oxide isOOBA′622, has eight molecules in the unit cell [3]. Pyrochlore oxides can display a remarkable variety of properties. They are interest for numerous applications including high efficiency catalysis [4], conduction of electricity, photoluminescence [5], resistance to radiation damage [1], and gas sensor [5]. In this study we have established a simple hydrothermal technique to prepare of a series of 722OSnBiSmxx−)0.2,0.1,0(=x pyrochlore nanocrystals by a low temperature hydrothermal method.
