單晶α-Al2O3、MgO、YSZ和TiO2在室溫下分別注入Ni＋和Zn＋離子，然后在氧化氣氛中退火，以形成金屬及其氧化物納米晶。形成的納米復合結構分別采用X射線光電子能譜(XPS)表征各元素化學價態；用X射線衍射分析(XRD)檢測納米結構的結晶形態；用透射電子顯微分析(TEM)觀察納米晶的微觀結構及分布情況；吸收光譜和熒光光譜分別用來表征納米復合結構的宏觀光學性能；超導量子干涉磁強計(SQUID)測量磁性納米晶的矯頑力及截止溫度。研究表明：在幾種單晶材料中分別形成的金屬Ni和Zn具有表面等離子共振吸收效應，ZnO納米晶具有較強的綠光發射，鐵磁性金屬Ni納米晶具有比常規塊材大的矯頑力。這些性能在光學濾波片、藍/綠發光器件和磁存儲器方面極具應用前景。

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
