纳米功能材料如发光材料（ZnS：Ag+，Cl-; LaPO 4：Ce 3+，Tb 3 +; Y 2 O 3：Eu 3+），彩色颜料（CoAl 2 O 4; Cr 2 O 3; ZnCo 2 O 4;（Ti0.85Ni0.05Nb0.10）O 2; α-Fe2O3; Cu（Fe，Cr）O-4;用多元醇法制备了透明导电氧化物（ZnO：In 3+）和催化活性氧化物（CeO 2; Mn 3 O 4; V2 O 5）。所有这些材料都以晶体、球形和几乎单分散的颗粒形式产生，尺寸为30-200 nm。进行表征的基础上，扫描电子显微镜（SEM），X射线粉末衍射（XRD），光谱，电导测量。通过多元醇方法的制备由于其广泛和容易的适用性而被挑选出来。由此产生的材料性能类似于或优于通过其他措施制备的纳米材料。一些材料及其性质，例如，首次在纳米尺度上呈现了作为荧光粉的ZnS：Ag+、Cl-、作为颜料的ZnCo 2 O 4和Cu（Fe，Cr）O-4以及作为透明导电氧化物的ZnO：In 3+。
Nanoscale functional materials such as luminescent materials (ZnS:Ag+, Cl-; LaPO4:Ce3+,Tb3+; Y2O3:Eu3+), color pigments (CoAl2O4; Cr2O3; ZnCo2O4; (Ti0.85Ni0.05Nb0.10)O-2; alpha-Fe2O3; Cu(Fe,Cr)O-4; TiO2), transparent conducting oxides (ZnO:In3+), and catalytically active oxides (CeO2; Mn3O4; V2O5) are prepared with the polyol method. All these materials are yielded as crystalline, spherical, and almost monodisperse particles, 30-200 nm in size. Characterization is carried out based on scanning electron microscopy (SEM), X-ray powder diffraction (XRD), optical spectroscopy, and conductance measurements. The preparation via the polyol method is singled out due to its broad and easy applicability. The resulting material properties are similar to or better than nanoscale materials prepared by other measures. Some materials and their properties, e.g., ZnS:Ag+,Cl- as a phosphor, ZnCo2O4 and Cu(Fe,Cr)O-4 as pigments, and ZnO:In3+ as transparent conductive oxide, are presented for the first time at the nanoscale.
