• Three‐dimensional, orthogonal lead sulfide (PbS) nanowire arrays and networks have been prepared by using a simple, atmospheric pressure chemical vapor deposition (APCVD) method. These uniform nanowires (average diameter 30 nm) grow epitaxially from the surface of the initial PbS crystal seeds and form orthogonal arrays and networks in space. The growth mechanism has been explored, and the process was classified as homogeneous, epitaxial growth in the 〈200〉 directions. Furthermore, Raman spectra of PbS nanowires are reported here, and their characteristic Raman peak (190 cm−1, no shoulder) could be used as a unique probe for the study of PbS nanomaterials. Homogeneous, epitaxial growth in the 〈200〉 crystal directions was displayed by PbS nanowires (see picture), which were prepared by using a simple, atmospheric pressure chemical vapor deposition method. The characteristic Raman peak (190 cm−1) of these nanowires could be used as a unique probe for the study of PbS nanomaterials.
