%X Oxide ion conductors have been studied for many 
years because of their application in devices with high 
economical interest such as solid oxide fuel cells, oxygen 
sensors , dense ceramic membranes for oxygen separation. In 
this paper nanopowders were synthesized via sol gel method. 
The sintering temperature to complete phase transition are 
above 500£¿c. As-prepared yttria doped Bi2O3 nanocrystals 
were characterized by X-ray diffraction (XRD) and 
transmission electron microscope (TEM). Transmission 
electron microscope (TEM) investigations revealed that the 
average particle size is less than 30 nm for these powders. It's 
worth noting that results show a good agreement of both 
methods. The morphology of the powders were observed on 
Field Emission scanning electron microscope (FESEM). Ionic 
conductivity measured by AC impedance spectroscopy.
