| 摘要: 以金属In和SnCl4·5H2O为主要原料，加入保护剂PVP，利用化学共沉淀法合成了球形的铟锡氧化物(ITO)纳米颗粒。分别对PVP的用量、溶液的pH值、热处理温度等因素对ITO纳米颗粒粒径的影响进行了分析。并且借助透射电镜(TEM)、X射线衍射(XRD)对所合成的ITO纳米颗粒进行了表征。XRD分析说明本文合成了金刚砂型结构的铟锡氧化物纳米颗粒，并且其晶型结构随着热处理温度的升高而转变为铁锰矿型。 |

| Abstract: Indium tin oxide nanoparticles were prepared by the co-precipitation method using Indium metal ingots and stannic chloride (SnCl4·5H2O) as the starting materials. The effect of the mass ratio of PVP to ITO, calcination temperature, solution acidity and the concentration of ITO on the ITO nanoparticles size was studied. Transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) were used to characterize the ITO nanoparticles. The XRD patterns showed that the ITO nanoparticles calcined at 450 ℃ was the corundum structure and changed to bixbyite structure when the calcination temperature increased to 550 ℃. |
