| 摘 要： | 采用化学气相沉积法,以纳米Mg2Si和SiO2的混合粉体作为硅源,在较低温度自组织生长了大量绳状SiOx新奇纳米结构。利用扫描电子显微镜、透射电子显微镜等手段对纳米结构进行了系统表征,并在室温观测到了光致发光,其发光峰峰位在560nm附近,在此基础上对该纳米结构的生长机理进行了深入的讨论。 |

| Abstract: | Self-assembly of rod-like SiOx(x=1~2) nanostructures were formed via chemical vapor deposition method by heating the Mg2Si and SiO2 nanoparticles mixture at low temperature. The nanostructures were analyzed by scanning electron microscopy, transmission electron microscopy, energy dispersive spectroscopy and low-energy electron diffraction methods. The photoluminescence (PL) characterization spectrum of the nanostructures showed a strong peak at 560 nm. Furthermore, the growth mechanism of the SiOx nanostructures was discussed qualitatively. |
| Keywords: | Si SiOx nanostructure self-assembly optical property |
