Abstract We have first demonstrated that SiO2 nanoparticles can be synthesized using an electron beam irradiation system in an ambient condition. The vibrational modes shown in FT-IR spectra, and the binding energy of Si 2p in X-ray photoelectron spectrum confirm that SiO2 nanoparticles were formed during the process. In this study, the average particle size of nanoparticles was reduced from 210 nm to 73 nm by reducing the residence time of the precursor vapor inside the reaction chamber by a factor of two indicating that our proposed method can be further used for the production of ultrafine aerosol nanoparticles.
