【期刊论文】Room temperature preparation of novel Cu2−xSe nanotubes in organic solvent
蒋阳, Yang Jiang , , YueWu, Bo Xie, Shuyuan Zhang and Yitai Qian
Nanotechnology 15(2004)283-286,-0001,():
-1年11月30日
A compound with a non-layered structure composed of Cu2−xSe nanotubes was prepared in a room temperature redox reaction in ethylene diamine solution. The product was characterized by x-ray diffractometry, transmission electron microscopy, high resolution transmission electron microscopy, and x-ray photoelectron spectroscopy. Analysis shows that the nanotubes have a multiwall structure with (002) planes of face-centred cubic Cu2−xSe and open ends. The Cu2−xSe nanotubes have length 500nm, with an inner diameter of 20nm and an outer diameter of 30nm on average. Ethylene diamine's ability to achieve strong coordination and the presence of the reducing agent hydrazine hydrate aid the formation of Cu2−xSe nanotubes with mixed valence.

Copper and silver nanocrystalline chalcogenides, Cu2 xSe, Cu2Te, Ag2Se, and Ag2Te, have been successfully synthesized in a mixture of ethylenediamine and hydrazine hydrate as a solvent at room temperature.Products showed different morphologies, such as nanotubes, nanorods, and nanoparticles.The results indicated that the coordination and chelation abilities of ethylenediamine play an important role in the formation of one-dimensional nanocrystalline binary chalcogenides, and hydrazine hydrate is crucial to the electron transfer in the room temperature reactions.These transition-metal nanocrystalline chalcogenides as prepared were analyzed by X-ray powder diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy.The UV-Vis absorption properties of these nanocrystals were also measured.

Uniform cubic-shaped PbS nanocrystals have been prepared by a hydrothermal reaction between Pb(Ac) 2. 2H2O and Na2S2O3 in the presence of surfactant of C17H33COOK. The product was characterized through XRD, TEM, and HRTEM. Essentially all the face-centered cubic phase of PbS nanocrystals are well-defined cube with (200) lattice planes as surfaces and easy to arrange orderly. r 2001 Published by Elsevier Science B. V.

【期刊论文】Zinc Selenide Nanoribbons and Nanowires
蒋阳, Yang Jiang, ‡ Xiang-Min Meng, † Wing-Ching Yiu, Ji Liu, Jun-Xian Ding, Chun-Sing Lee, and Shuit-Tong Lee*
J. Phys. Chem. B 2004, 108, 2784-2787,-0001,():

Zinc selenide nanoribbons and nanowires were obtained using laser ablation of ZnSe pressed powders. Their formation appeared to follow the vapor-solid and vapor-liquid-solid growth mechanisms, respectively. The product was characterized by means of scanning electron microscopy, transmission electron microscopy, micro-Raman scattering, and energy-dispersive X-ray spectroscopy. The ZnSe nanoribbons had a perfect wurtzite-2H single-crystal structure with a [120] growth direction and the {001} close-packed lattice planes of hexagonal ZnSe stacking along the nanoribbon width axis. The ZnSe nanowires grew with the {001} close-packed lattice planes of the wurtzite-2H structure stacking along the nanowire length axis. Both the longitudinal optic (LO) and transverse optic (TO) phonon peaks of the ZnSe nanowires and nanoribbons showed a clear shift toward low frequency relative to bulk values, probably because of small size and large surface effects. The ZnSe nanostructures exhibited strong self-activated luminescence centered at 596nm.

【期刊论文】Room-temperature single nanoribbon lasers
蒋阳, J. A. Zapien, Y. Jiang, X. M. Meng, a) W. Chen, F. C. K. Au, Y. Lifshitz, b) and S. T. Lee c)

Using a single nano-object measurement methodology that enables the correlation between size/ morphology/structure and photoluminescence (PL) characteristics, we show that nanoribbons are an excellent model system to study single nano-objects. In particular, we measure the PL characteristics of optically pumped individual single-crystal zinc-sulfide nanoribbons. Small collection angle measurements show that nanoribbons form excellent optical cavities and gain medium with high (full width at half maximum, 0.1nm) lasing modes free of PL background even for a low pumping power density of 9kW/cm2. Large collection angles add a broad PL component and obscure the correct high-quality lasing of the nanowires/nanoribbons.

Here, we report a form of nanostructures bicrystal nanoribbons. Zinc sulfide ZnS bicrystal nanoribbons were prepared via simple thermal evaporation of a powder mixture of ZnS and SiO. The product was characterized with transmission electron microscopy TEM, high-resolution TEM, and electron energy loss spectroscopy. The ZnS bicrystal nanoribbons have widths of 50-500nm and lengths of several tens of micrometers. Two kinds of growth direction, i. e. @21221# and 21231#, have been found. The growth of the ZnS bicrystal nanoribbons was considered to involve a combination of oxide-assisted and vapor-liquid-solid processes.

【期刊论文】Elemental Solvothermal Reaction To Produce Ternary Semiconductor CuInE2 (S, Se) Nanorods

The synthesis of nanostructure semiconductors has been of interest to material scientists and chemists because of their potential applications in recent years. 1-4 I-III-VI2 ternary semiconductor compounds such as CuInSe2 and CuInS2 with thechalcopyrite structure have been shown to be useful as nonlinear optical and direct energy gap materials. 5, 6 Previous synthesis routes proposed for CuInSe2 and CuInS2 include electrodeposition, 7, 8 high-pressure Se vapor treatment,9 H2Se treatment of Cu-In alloys, 10 ionized cluster beam technique, 11 metal organic chemical vapor deposition (MOCVD), 12 and reaction between CuCl2, InCl3, H2SeO3 in aqueous solution.13 However, these conventional routes usually need either a high temperature and long time or special devices, and some even require toxic reagents. Attention is currently focused on developing new methods for the preparation of nanoparticles and nanofilms. 14, 15 Herein we report a convenient method for the synthesis of CuInSe2 and CuInS2 nanorods from the elements under a solvothermal process.

A La(OH)3 gel solvothermal process has been developed for the preparation of nanocrystalline lanthanide oxysulfide (La2O2S) in polar solvents at 300℃ through a reaction between a La (OH)3 gel and K2S. X-ray powder diffraction (XRD) indicated that the product was hexagonal La2O2S with cell parameters a 5 4.046 Å and c 5 6.951 Å. Transmission electronic microscopy (TEM) showed that different morphology nanocrystallites were formed, including particles with diameters of about 10nm and nanorods about 10nm in diameter and 300nm in length, depending on the solvent.
