Microwave-assisted elemental direct reaction route to nanocrystalline copper chalcogenides CuSe and Cu2TeElectronic supplementary information (ESI) available: XPS spectra of the products. See http://www.rsc.org/suppdata/jm/b2/b205558a/

Abstract

Nanocrystalline copper chalcogenides, CuSe and Cu₂Te, have been synthesized by reactions between elemental Cu and Se or Te under microwave irradiation for several minutes. The products have been characterized by XRD, TEM, and XPS.
