Abstract

Abstract: High-density, large-scale SiO_x(x≤2) nanowires were successfully fabricated using carbon-assisted CVD method with Fe-Al-O catalyst at 1100—1140 ℃, under a flowing N₂/H₂ atmosphere. The SiO_x nanowires are uniform with a diameter of 30—200 nm and a length of up to a few handrand micrometers. SEM, TEM, EDS, FTIR and PL were preformed to characterize the microstructure, composition and optics performances of the nanowires. The nanowires show IR absorption peaks at 482, 806, 1095 and 1132 cm^-1. The PL peak of the nanowires is at 438 nm.

Key words: SiO_x(x≤2) nanowire, Carbon-assisted CVD method, FTIR spectrum, PL spectrum
