中文摘要：

将100 keV,剂量为5×10~（16）/cm~2的Cu离子和65 keV,剂量为5×10~（16）/cm~2的Zn离子单独或顺次注入到无定形SiO2中,并在氮气中热处理,研究了Cu-Zn合金纳米颗粒（NPs）的合成、热演变及其光学性质。结果表明：通过离子注入法将顺次注入Cu和Zn离子的样品在注入态形成了Cu-Zn合金NPs,并在520 nm附近产生了表面等离子共振（SPR）吸收峰。热处理后,合金的SPR吸收峰增强并蓝移;直至800℃时,Cu-Zn合金才分解。Cu-Zn合金NPs能够在700℃稳定存在,同时具有很好的三阶非线性光学性质。

英文摘要：

Amorphous SiO2 slices were sequentially implanted with 100 keV Cu ions at fluence of 5.0 × 1016 ions/cm2 and 65 keV Zn ions at fluence of 5.0 × 1016 ions/cm2, and were subsequently subjected to thermal annealing in nitrogen atmosphere at different temperatures. The synthesis, thermal stability and optical properties of Cu-Zn alloy nanoparticles （NPs） were investigated. The Cu-Zn alloy NPs were synthesized via the dual ion implantation of Cu and Zn ions causing a unique surface plasmon resonance（SPR） absorption peak at 520 nm. The SPR absorption peak is increased and shifted toward the short wavelengths after subsequent annealing The Cu-Zn alloy NPs are decomposed after thermal annealing at 800℃. The sample has a superior third-order nonlinear optical property after thermal annealing at 700 ℃.
