| 英文摘要 | Nearly monodispersed self-assembled tin dioxide (sno2) nanospheres with intense photoluminescence (pl) were synthesized using a new wet chemistry technique. instead of coprecipitating stannous salts, bulk tin (sn) metal was oxidized at room temperature in a solution of hydrogen peroxide and deionized water containing poly vinylpyrrolidone (pvp) and ethylenediamine (eda). sno2 nanocrystals were produced with diameters of similar to 3.8 mn that spontaneously self-assembled into uniform sno2 nanospheres with diameters of similar to 30 nm. analysis was performed by x-ray diffraction, scanning electron microscopy, energy-dispersive x-ray spectroscopy, high-resolution transmission electron microscopy, selected area electron diffraction, x-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, uv-vis absorption spectroscopy, pl spectroscopy, and fluorescence lifetime measurements. the sno2 nanospheres displayed room-temperature purple luminescence with an intense band at 394 nm (similar to 3.15 ev) and a high quantum yield of similar to 15%, likely as a result of emission from the surface states of sno2/pvp complexes. the present study could open a new avenue to large-scale synthesis of self-assembled functional oxide nanostructures with technological applications as purple emitters, biological labels, gas sensors, lithium batteries, and dye-sensitized solar cells. |
