Control synthesis of semiconductor ZnSe quasi-nanospheres by reverse micelles soft template

Semiconductor ZnSe quasi-nanospheres have been successfully prepared by the reaction between Zn2+ and Se2- under the induction of reverse micelles soft template. The products were characterized by X-ray diffraction, transmission electron microscopy and photoluminescence. XRD and TEM revealed that the products were spherical and homogeneous with cubic structure, which ranged from 200 nm to 300 nm in diameter. The corresponding photoluminescence peaks showed a red shift compared to bulk ZnSe. The possible formation mechanism was investigated. (c) 2005 Elsevier B.V All rights reserved.
