SnO2 nanoparticles embedded in silica by ion implantation followed by thermal oxidation. Tagliente, M., Bello, V., Pellegrini, G., Mattei, G., Mazzoldi, P., & Massaro, M. JOURNAL OF APPLIED PHYSICS, 2009. doi abstract bibtex Nanoparticles of tin dioxide embedded in silica matrix were synthesized by ion implanting a Sn(+) ion beam in a silica slide and by annealing, in oxidizing atmosphere at 800 degrees C. A detailed structural and optical characterization was performed by using glancing incidence x-ray diffraction, transmission electron microscopy, optical absorption, and photoluminescence spectroscopies. Metallic tetragonal, beta-tin crystalline nanoparticles were formed in the as-irnplanted sample. The annealing in oxidizing atmosphere promotes the total oxidation of the tin nanoparticles with a preferential migration of the nanoparticles toward the surface of the matrix. A broad blue-violet emission band peaked at 388 nm was observed in the photoluminescence spectra of both the as-implanted and annealed samples, which was attributed to the Sn-related oxygen deficiency center defects and the SnO(2) nanoparticles, respectively.
