利用TEM、XRD、XPS、DSC、TGA和UV-Vis-NIR系统研究了氧分压（0.5×103Pa至4×103Pa）对在流动Ar+O2气氛中通过混合感应和激光加热（HILH）方法从纯锑蒸发的Sb2O3纳米粒子的合成和特性的影响 光谱测定法。合成的 Sb2O3 纳米粉末由平均尺寸约为 80 nm 的小球形颗粒组成。随着氧分压从0.5×103Pa增加到4×103Pa，纳米粉体中金属Sb的含量显着降低。 Sb2O3纳米颗粒在可见光和360至2500nm范围内的所有远红外光范围内的光学性能和热特性都强烈依赖于氧分压。
Influence of the oxygen partial pressure (0.5×103Pa to 4×103Pa) on synthesis and characteristics of Sb2O3nanoparticles evaporated from the pure antimony by means of hybrid induction and laser heating (HILH) method in a flowing Ar+O2atmosphere has been systematically investigated using TEM, XRD, XPS, DSC, TGA, and UV-Vis-NIR spectrometry. The as-synthesized Sb2O3nanopowder consists of small spherical particles with an average size of approximately 80nm. As the oxygen partial pressure increases from 0.5×103Pa to 4×103Pa, the metallic Sb content in the nanopowder was decreased markedly. Both optical property at visible and all far infrared light scope ranging from 360 to 2500nm and thermal characteristic of the Sb2O3nanoparticles are strongly dependent on the oxygen partial pressure.
