Abstract
SiO 2 amorphous nanoparticles have been successfully synthesized on the surface of the SiO 2 amorphous nanowires via a thermal evaporation method using SiO powders as the source agents. The as-synthesized products have been systematically studied by X-ray powder diffraction (XRD), Raman spectroscopy (RS), scanning electron microscope (SEM), electron energy-dispersive X-ray (EDX) and photoluminescence (PL). The results indicate that SiO 2 amorphous nanoparticles grown on the amorphous nanowires at the temperatures of 1135 °C. Furthermore, The RT PL spectral results reveal the obtained composite structures have a stable and strong yellow-green emission range. The products are available for the applications in optoelectronic semiconductor devices with improving performances.
