SrTiO3 nanorods were synthesized in cetanyl trimethyl ammonium bromide(CTAB)reverse microemulsion containing CTAB,n-hexanol,n-octane and water with Ba(OH)2 as reactants.The effects of different conditions such as ω0 [ω0=n /nCTAB],aging time and the concentration of reactants on the formation of the nanorods were studied.Transmission electron microscope(TEM),electron diffraction(ED)and X-ray diffraction(XRD)were used to characterize the morphology and the structure of the synthesized nanorods.The results show that SrTiO3 nanorods with a length of 260～2 000 nm and a diameter of 50～100 nm belonging to single crystal are single cubic system.The molar ratio of Sr to Ti of products is 1.0 as determinded by ICP.
Lead iodide nanorods with a length of 500—3200 nm and a diameter of 35—130 nm were synthesized in an inverse microemulsion system consisting of water,Triton X-100,cyclohexane and n-hexanol.The prepared products were characterized via TEM and XRD.The results show that ω0(the molar ratio of water to surfactant),the concentration of reactants,reaction temperature and aging time all can affect the morphology and size of the lead iodide nanorods prepared.The as-prepared nanorods belong to hexagonal system.
