| 1 | Synthesis and Purple-Blue Emission of Antimony Trioxide Single-Crystalline Nanobelts with Elliptical Cross Section显示文摘Single-crystalline orthorhombic antimony trioxide(Sb_(2)O_(3))nanobelts with unique elliptical cross sections and purple-blue photoluminescence have been synthesized.The uniform Sb2O3 nanobelts are 400600 nm in width,2040 nm in thickness at the center and gradually become thinner to form sharp edges sub-5 nm in size,tens of micrometers in length,and with[001]as the preferential growth direction.Self-assembly of tens of nanobelts into three-dimensional(3-D)flower-like nanostructures has been observed.Analysis was performed by X-ray diffraction,energy-dispersive X-ray spectroscopy,X-ray photoelectron spectroscopy,scanning electron microscopy,high-resolution transmission electron microscopy,selected area electron diffraction,Raman spectroscopy,Fourier transform infrared spectroscopy,and photoluminescence spectroscopy.The Sb_(2)O_(3) nanobelts display intense purple-blue photoluminescence centred at 425 nm(~2.92 eV).The successful synthesis of nanobelts with elliptical cross sections may cast new light on the investigation of the property differences between nanobelts with rectangular cross sections and those with other cross section geometries.The Sb2O3 nanobelts can be used as effective purple-blue light emitters and may also be valuable for future nanodevice design. | Zhengtao Deng Dong Chen Fangqiong Tang Jun Ren Anthony J.Muscat | 2009 | Nano Research2009，2，2： | 2 |
