| Abstract: | Single phase Bi2Te3 nanoflakes with hexagonal morphology were synthesized with solvothermal method by using glycol as solvent with appropriate content of polyvinylpyrrolidone(PVPK-30) added in.Reaction was performed in alkalinous environment at 200℃ for 260 minutes.X-ray powder diffraction(XRD),scanning electron microscope(SEM),photoluminescence spectrum(PL),and ultraviolet-visible absorption spectroscopy(U-VAS) were used to characterize the crystal structure,morphology and optical properties of these nanoflakes. |
