| Abstract: | La-doped BaTiO_3 nanocrystal was prepared by Sol-Gel processes. The morphology and defects of Ba_(1-x)La_xTiO_3 was analyzed with TEM and positron annihilation technique.The results showed that the doping of La resulted in the expansion of crystal lattice and the formation of VBa" within 0
