Abstract

SiC/Sio₂ one-dimensional nanochains and SiC/SiO₂ two-dimensional X-junction and Y-junction nanochains were synthesized by using a simple and low-cost microwave method. Structural, morphological, and elemental analysis revealed that the SiC/Si0₂ nanochains consisted of 3C-SiC strings with diameters of 20-80 nm and periodic Si0₂ beads with diameters of 100-400 nm. Spectral analysis indicated that both SiC strings and SiO₂ beads produced significant photoluminescence, and the presence of SiO₂ beads enhanced the emissions from SiC strings. On the basis of experimental characterizations, a two-step growth mechanism of the nanochains was proposed to elucidate the growth process.
