| Abstract: | Single crystal Na0.5Bi0.5TiO3 nanorods were synthesized by a novel method of sol-gel-hydrothermal under certain conditions.The advantages of this method included the controllability of elements composition and non-volatilization for Bi and Na ions.The phase,morphology,microstructure and optical absorption property were characterized by using XRD,SEM,TEM and UV/vis absorption spectrum technologies.The results showed that the as-prepared Na0.5Bi0.5TiO3 nanorods were thombohedral perovskite phase,with the energy band of about 3.38 eV.Blue shifts happened with the UV/vis absorption spectrum as comparing the Na0.5Bi0.5TiO3 nanorods with macrograin materials. |
