N2 - Antimony-doped tin oxide (ATO) nanophase materials containing up to 43 mole% antimony have been synthesized by a wet-chemistry method. These ATO materials exhibit enhanced electrochromic properties for display devices. The performance of the display devices is related to the nanostructure of the synthesized ATO materials. The average sizes of the ATO nanocrystallites depend on dopant level, annealing conditions, and synthesis processes. Antimony inhibits the growth of tin dioxide nanocrystallites during annealing at moderate temperatures. At higher annealing temperatures, however, antimony segregates to form separate oxide phases and ATO nanocrystallites grow significantly. A systematic study of the structural evolution of the synthesized ATO materials is presented and the relationship between the nanostructure of the ATO materials and the enhanced performance of the corresponding electrochromic devices is discussed.

Synthesis of monodispersed mesoporous tin oxide spheres and fabrication of close-packed mesoporous tin oxide opal is presented. By taking advantage of the oxidation of tin(II) chloride on the surface of monodispersed starburst carbon spheres (MSCS), which are produced using monodispersed mesoporous silica spheres as a host, nanocrystals of tin oxide accumulate into mesopores of MSCS. Calcination of the MSCS/SnO2 composite yields monodispersed mesoporous tin oxide spheres (MMTOS) that consist of SnO2 nanocrystals. Although the starburst structure of MSCS is lost during calcination, monodispersed spherical shape is retained. As a result of its uniformity, MMTOS can be self-assembled into a close-packed opal, which exhibits a stop band in the visible region.

Tin(IV) oxide nanoparticles were synthesized via the reaction of carbon dioxide with stannate ions immobilized by dendritic polymers. For PAMAM and PPI dendrimer hosts, resultant nanoparticle diameters were 2.5−3 nm; 3−3.5 nm nanoparticles resulted from use of a poly(ethyleneimine) hyperbranched polymer. Our conditions represent the only precedent for SnO2 nanoparticulate growth using dendritic architectures, as well as a novel application for CO2 as a reactive gas for the controlled growth of metal oxide nanoparticles.

Synthesis of tin Oxide Nanoparticles by Mechanical Reaction

Tin oxide powders of nanometer size have been synthesized by a gas condensation method using helium or a mixture of oxygen and helium as the convection gas. Changes in the average size, morphology, and crystal phases were investigated during heat treatment at temperatures between 350°C and 720°C in the air. Spherical tin oxide powders of 15 nm in average diameter were synthesized in a helium atmosphere, which was composed of Sn, SnO, and Sn2O3, phases. After annealing at 720°C, these multiphase particles transformed to a single SnO2 phase and became an irregular shape of about 50 nm in diameter. This rapid coarsening was attributed to fast mass transfer among particles. The spherical SnO2 powder of 7 nm in average diameter was directly synthesized using a gas mixture of oxygen and helium. Upon annealing up to 720°C, morphological changes were barely observed in the powder synthesized using a convection atmosphere containing oxygen.
