在SiO2纳米球表面制备了以1，4-BDT分子为间隔基的银包覆金纳米壳（Ag/BDT/Au）。通过调节Au和Ag纳米壳层的厚度，对单壳层和双壳层Au/SiO2和Ag/BDT/Au/SiO2纳米粒子的表面等离子体共振进行了调谐。通过测量拉曼散射和非线性折射，证实了Au和Ag壳层的差距中的局域场增强。结果表明，由于Ag壳层的生长，拉曼强度增强了17倍，非线性折射率增强了30%。
Silver-coated gold nanoshells with 1,4-BDT molecules as the spacer (Ag/BDT/Au) were synthesized on the surface of SiO2nanospheres. The surface plasmon resonance of Au/SiO2and Ag/BDT/Au/SiO2nanoparticles with single and double shells were tuned by adjusting the thickness of Au and Ag nanoshells. The enhanced local field in the gap of Au and Ag shells is demonstrated by measuring Raman scattering and nonlinear refraction. The results show that the Raman intensity is enhanced by 17 times and the nonlinear refractive index is enhanced by 30 % due to the growth of Ag shells.
