在聚乙烯醇存在下，以SbCl_3和NaOH为原料，在水溶液中合成了纳米锑氧化物。颗粒的尺寸在10 ~ 80 nm之间，最大的可达200 nm，在回流的初始阶段可能开始生长。透射电子显微镜和高分辨电子显微镜（HREM）被用来表征这些纳米粒子的微观结构。用硅单晶作内标，多晶衍射图分析表明，只有立方Sb_2O_3相存在。明场显微照片显示颗粒可能具有各种多面体构型。HREM结果表明，颗粒是结晶完美的。此外，还对纳米粒子的形成机理进行了探讨。
Antimony oxide nanoparticles were synthesized in the presence of the polyvinyl alcohol in water solution through the reaction between SbCl_3 and NaOH. The size of the particle ranges from 10 to 80 nm, and the largest one can even reach 200 nm, which may begin to grow in the initial stage of the reflux. Transmission electron microscopy and high-resolution electron microscopy (HREM) were used to characterize the microstructure of these nanoparticles. Using silicon single crystals as internal standards, the polycrystalline diffraction pattern analysis shows only presence of cubic Sb_2O_3 phase. The bright-field micrograph displays that the particles may have various polyhedral configurations. HREM results show that the particles are crystallographically perfect. Moreover, the formation mechanism of nanoparticles is discussed.
