Based on 30keV silver ions at a fluence of 6נ10¹⁶ionscm⁻² implanted into SiO₂, Al₂O₃ and YAG, we found that the nanocomposite layers embedded with silver nanoparticles are sensitive to the refractive index of overlays on the implanted surface. By dropping liquids with different refractive indices on the surface of nanocomposite layer, the reflection spectra of the rear surface would shift. The sample with YAG as the substrate has better performance by comparing with the other two samples. The prepared structures have the advantages of simple structure and stable performance, which has potential applications in localized surface plasmon resonance sensors.

基于注入到SiO ₂，Al ₂ O ₃和YAG中的6 × 10 ¹⁶ ionscm ^-2的通量的30keV银离子，我们发现嵌有银纳米颗粒的纳米复合材料层对注入表面上的覆盖层的折射率敏感。通过将具有不同折射率的液体滴到纳米复合层的表面上，后表面的反射光谱将发生偏移。与其他两个样品相比，以YAG为底物的样品具有更好的性能。所制备的结构具有结构简单，性能稳定的优点，在局部表面等离子体共振传感器中具有潜在的应用前景。
