| 摘 要： | 利用溶胶凝胶法制备Ni掺杂AZO(NAZO)纳米粉体。通过TG-DSC、XRD、TEM、XPS等分析手段,研究掺杂浓度和煅烧温度对纳米粉体结构和电学性能影响规律。结果表明:在600℃下煅烧2 h,NAZO纳米粉体具有六角纤锌矿结构,粉体的粒径约25~35 nm,主要呈现球状和棒状结构。当铝掺杂摩尔百分比为1 mol%,镍掺杂摩尔百分比为1.5 mol%时,纳米粉体的电阻率为4.309 M?·cm。

| Abstract: | Ni doped AZO （NAZO） nanoparticles was prepared by sol-gel method. The crystallization properties, conductivity and composition of NAZO were characterized by X-ray diffraction（XRD）, Transmission electron microscopy（TEM） and X-ray photoelectron spectroscopy（XPS）, respectively. When samples calcined in an air ambient at 600 ℃ for a period of 2 h, It shows that all the nanoparticles exhibit the hexagonal wurtzite structure. The diameter of NAZO nanoparticles was various from 25-35 nm. It was known that the NAZO nanoparticles with lowest resistivity 4.309 MΩ-cm was obtained when AI doping concentration was 1 mol% and Ni doping concentration was 1.5 mol%. |
