摘要：
ZnSe nanodonuts with outer diameters ranging from 0.5 to 1.5 mu m and the wall thickness in the range of 100-300 nm were synthesized by a simple and convenient surfactant-assisted process. XRD and TEM results show the as-prepared sample is single crystalline zinc blende ZnSe. The formation mechanism of the ZnSe nanodonuts has been discussed. Polyethylene glycol (PEG) and hydrazine hydrate play key roles in the forming the donut-like shape of ZnSe. This method may be extended to fabrication of donut-like nanostructure of other chalcogenides. (C) 2008 Elsevier Ltd. All rights reserved.
