摘要

得到了金属纳米片的横向和纵向q因子与频率和尺寸的关系。结果表明，在可见光谱中，Au和Ag圆盘的q因子大于其他金属圆盘的q因子，并且随着长宽比的增大而增大。结果表明，当频率接近表面等离子体共振频率时，银纳米片的q因子最大，且横向q因子显著大于纵向q因子。

Quality Factor of the Surface Plasmonic Resonance in the Metallic Nanodiscs

The frequency and size dependences for the transverse and longitudinal Q-factor of the metallic nanodiscs have been obtained. It has been shown that Q-factor of the discs Au and Ag in the visible spectrum is greater than Q-factor for the discs of other metals and it increases under the increase of the aspect ratio. It has been established that the silver nanodiscs have the greatest Q-factor when the frequencies are close to the frequencies of the surface plasmonic resonance, and the transverse Q-factor is greater than the longitudinal Q-factor significantly.
