理论研究了金纳米球壳结构局域表面等离子体共振（LSPR）的调谐特性。结果表明，对于固定内径的球壳结构，利用杂化效应使得球壳结构可通过改变其厚度实现LSPR峰位的调控，并可保持较窄的谱宽；而对于不同内径的球壳，在LSPR调控过程中，随壳层厚度与球壳内半径比值的减小，吸收光谱在消光光谱中所占比例增大。不仅如此，利用杂化效应进行偶极峰位调控时所能获得的峰位调控范围与球壳内径有关，内径越大，所能获得的偶极峰位调控范围越大。

Tunable characteristics of the localized surface plasmon resonance (LSPR) peak of gold nanoshells are investigated numerically with Mie theory. The results show that, for a nanoshell with fixed inner radius, the LSPR peak of gold nanoshell may be controlled by changing the thickness of the shell to adjust the strength of the hybridization effect which makes the LSPR peak red-shift. As the ratio of the nanoshell thickness to the nanoshell inner radius decreases, the absorption component in whole extinction spectra for nanoshells with different inner radii all increases. In addition, when the hybridization effect is used to adjust the LSPR dipole peak position, the available maximum wavelength scope is determined by the nanoshell inner radius. The larger the inner radius is, the wider the available maximum wavelength scope is.
