Amorphous SiO2 Nanoparticles Grown on the Surface of the Nanowires

SiO2 amorphous nanoparticles have been successfully synthesized on the surface of the SiO2 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 SiO2 amorphous nanoparticles grown on the amorphous nanowires at the temperatures of 1135 degrees 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.
