Abstract

We have observed the compensation of loss in a metal by a gain in a dielectric medium in the mixture of an Ag aggregate and a Rhodamine 6G dye. The demonstrated sixfold enhancement of the Rayleigh scattering is the evidence of the enhancement of the surface-plasmon resonance. The reported experimental observation facilitates many applications of nanoplasmonics.

摘要

我们已经观察到，在银聚集体与罗丹明6G染料的混合物中，通过电介质介质中的增益来补偿金属中的损失。所展示的瑞利散射增强六倍是表面等离子体共振增强的证据。所报道的实验观察结果促进了纳米等离子体学的许多应用。
