论文摘要
我们研究了通过偶极模式的模式形成的偶极运动模式的影响，该模式具有纳米格的高阶表面等离子体模式对辐射衰减速率和nanoegg附近激发分子的量子产率的影响。遵循Gersten-Nitzan和Ford-Weber方法，研究了发射极的purcell因子，发射极的功率耗散速率，纳米noegg的天线效率以及发射极的量子提高。与同心纳米壳相比，我们表明介电核金属壳纳米noegg是一种更有效的等离激元纳米annoantenna，用于辐射衰减率提高单个发射器。发现发射极的量子产率在纳米壳附近增加了增强，而在纳米g中发现其排放率更高。
We investigate the impact of the dipole-active modes formed via the mode-mixing of the dipole mode with higher-order surface plasmon modes of a nanoegg on the radiative decay rate and quantum yield of an excited molecule near the nanoegg. The Purcell factor, rate of power dissipation by the emitter, antenna efficiency of the nanoegg, as well as quantum yield enhancement of the emitter, were studied using the quasistatic approximation and the semiclassical theory of radiation, following the Gersten-Nitzan and Ford-Weber approaches. Compared to the concentric nanoshell, we show that the dielectric core-metallic shell nanoegg is a more efficient plasmonic nanoantenna for radiative decay rate enhancement of single emitters. The quantum yield of the emitter was found to be more enhanced near the nanoshell, while its emission rate was found to be more enhanced near the nanoegg.
