摘 要：Triangular-pyramidal ω-Bi2O3 is successfully synthesized via a one-step wet-chemical method.XRD,SEM,and UV-vis have been employed to characterize the as-prepared samples.Structural characterization by XRD confirms the formation of triclinic ω-Bi2O3 with high purity.The well-defined flowerlike Bi2O3 structures consisted of many triangular-pyramids are formed.Preparative parameters,such as concentration of PEG 6000,have great effects on the morphology and the particle size.The obvious absorption edge for ω-Bi2O3 powder is located at about 493 nm,which corresponds to the optical band gap energy of2.73 eV.
