利用TDLDA方法，我们研究了金原子的d电子极化率如何影响金属纳米壳的电子和光学性质。结果表明，极化的凝胶背景可以引起等离子体共振的显著偏移。研究结果表明，理论计算的含硫化金核的金纳米壳的光吸收光谱与实验数据吻合良好。
Using the TDLDA method, we investigate how the polarizability of the d electrons of the gold atoms influences the electronic and optical properties of metallic nanoshells. It is shown that a polarizable jellium background can introduce a significant shift of the plasmon resonances. The results of the study show that the theoretically calculated optical absorption spectra for gold nanoshells with a gold sulfide core are in excellent agreement with experimental data.
