Bundled one-dimensional Si3N4 single-crystalline nanowires are successfully synthesized by pyrolysis of a polymer precursor using Fe as catalyst. The average diameter of the obtained Si3N4 nanowires is about 200 nm, and the nanowires have perfect single-crystalline structure. Intense photoluminescence was observed centered at 1.83, 2.79, 3.24, and 3.74 eV. The nanowires could be useful in the fabrication of optoelectronic nanodevices and nanocomposites.
