Description:

We report an eco-friendly synthesis of well–controlled, nano-to-micron-size, spherical SiO2 particles using non-hazardous solvent and a byproducts-producing system. It was found that the morphology and size of spherical SiO2 particles are controlled by adjusting the concentration of PEG and oleylamine, ethanol solvent selection, and reaction temperature. The SEM images show spherical-shaped silica particles with homogeneous particle-size distribution. Structural and optical properties of the silica particles were investigated by FT-IR absorption spectroscopy and photoluminescence. The resultant SiO2 particles from the synthesis system were easily dispersed in both water and organic solvent.
