PbSe nanowires with an average size of 8 × 350 nm were synthesized by the reaction of Pb(NO 3 ) 2 and Se powder at 60 °C under ambient pressure. A mixture of arachidic acid (AA, n ‐C 19 H 39 COOH) and octadecylamine (ODA), which could form a complex with Pb 2+ , was employed as a soft template to control the morphology of the resultant PbSe nanowires. The products were characterized by X‐ray powder diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and transmission electron microscopy. The photoluminescence (PL) spectrum of the PbSe nanowires is presented. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
