Synthesis and Shape Control of CulnS Nanoparticles.
CuS-CulnS hybrid nanostructures as well as pure CulnS (CIS) nanocrystals were synthesized by methods of colloidal chemistry. The structure, the shape and the composition of these nanomaterials were investigated with transmission electron microscopy (TEM), powder X-ray diffraction (XRD) and energy di...

The structure, the shape and the composition of these nanomaterials were investigated with transmission electron microscopy (TEM), powder X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDX). By changing the reaction conditions, CulnS nanorods with different aspect ratio, dimeric nanorods as well as hexagonal discs and P-shaped particles could be synthesized. Under our reaction conditions, CIS nanoparticles crystallize in the hexagonal wurtzite structure, as confirmed by Rietveld analysis of the X-ray diffraction patterns. The formation of CuS-CulnS hybrid nanostructures turned out to be an essential intermediate step in the growth of CIS nanoparticles, the copper suiphide part of the hybrid material playing an important role in the shape control of the CIS nanocrystals. By a treatment of CuS-CulnS with 1,10-phenanthroline, CuS parts of the hybrid nanostructures could be removed, and pure CIS nanoparticles with shapes not accessible with other methods can be obtained. Our synthetic procedure turned out to be suitable to synthesize also other compounds, like CulnS-ZnS alloys, and to modify, in this way, the optical properties of the nanocrystals. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2010 holdings: @attributes: islocal: N |
