利用20 keV的He离子注入表面蒸镀了Au薄膜的尖晶石(MgAl_2O_4)样品,随后对注入样品进行了退火处理.在紫外可见光谱上观察到了由于金属纳米颗粒的存在而引起的较强的表面等离子体共振吸收峰,提供了材料中金属纳米颗粒形成的光谱证据.并对形成的Au纳米颗粒的尺寸随退火温度以及He注入剂量的变化进行了研究.
Spinel deposited with a thin Au film was implanted with helium ions, and annealed in vacuum condition subsequently. The surface Plasmon resonance absorbance peak due to the existence of metallic nanoparticles in the dielectric matrix was observed on the Ultraviolet-Visible Spectrometry, indicating the formation of metallic nanoparticles in spinel. The dependence of Au particles size with annealing temperature and implantation doses was also investigated.
