单晶α-Al2O3、MgO、YSZ和TiO2在室温下分别注入Ni＋和Zn＋离子，然后在氧化气氛中退火，以形成金属及其氧化物纳米晶。形成的纳米复合结构分别采用X射线光电子能谱(XPS)表征各元素化学价态；用X射线衍射分析(XRD)检测纳米结构的结晶形态；用透射电子显微分析(TEM)观察纳米晶的微观结构及分布情况；吸收光谱和荧光光谱分别用来表征纳米复合结构的宏观光学性能；超导量子干涉磁强计(SQUID)测量磁性纳米晶的矫顽力及截止温度。研究表明：在几种单晶材料中分别形成的金属Ni和Zn具有表面等离子共振吸收效应，ZnO纳米晶具有较强的绿光发射，铁磁性金属Ni纳米晶具有比常规块材大的矫顽力。这些性能在光学滤波片、蓝/绿发光器件和磁存储器方面极具应用前景。Ni+ and Zn+ ion implantations were performed at room temperature in α-Al2O3, MgO, YSZ, and TiO2 single crystals and then annealed in oxidized atmosphere in order to fabricate metal and its oxide nanoparticles. The micro-structural and macro-properties of nanocomposites were examined by different methods: X-ray Photoelectron Spectroscopy(XPS), X-Ray Diffraction(XRD), Transmission Electron Microscopy(TEM), optical spectroscopy, and Superconducting Quantum Interference Device (SQUID) magnetometer, respectively. Metallic Ni and Zn nanoparticles have special Surface Plasma Resonance(SPR) absorption. ZnO nanoparticles in α-Al2O3 showed a strong green emission band. The coercive force of ferromagnetic Ni nanoparticles was larger than that of bulk materials of Ni. These properties may provide potential applications in optical filters, green/blue light-emitting devices and high density magnetic data storage devices
