摘要：

In this letter, we successfully synthesize CuxS nanowires by sulfuring the copper nanowires at varied temperatures. When the annealing temperatures reach 400, 450, and 500 degrees C, the x values are equal to 1.03, 1.26, and 1.43, respectively. The CuxS nanowire arrays are highly ordered and have high wire packing densities. At 400 degrees C sulfured temperature, the CuS nanowire phase with a strongly preferential peak [110] indicates that the nanowire arrays should point to the [110] direction. The UV-vis spectroscopy measurement shows only one broad absorption peak that appears at 802 nm in near-IR region. This proves that the sulfured nanowire has pure CuS phase. (C) 2007 Elsevier B.V.
