摘要

在这项工作中，我们对混合等离子体系统进行了系统研究，以阐明控制荧光增强过程的机制的新见解。我们利用双曲元天线研究了CdSe/ZnS量子点的发射特性。通过在等离子体天线内部引入一个介电层，我们设计了吸收和散射光谱。我们用光刻技术定义了具有不同直径的元天线作为接收和发送纳米天线，以有效地耦合量子点的光致发光。

Plasmon-modulated photoluminescence of the photoexcited hyperbolic meta-antennas

In this work, we performed a systematic study on a hybrid plasmonic system to elucidate a new insight into the mechanisms governing the fluorescent enhancement process. We have used hyperbolic meta-antennas to study the emission properties of CdSe/ZnS quantum dots (QDs). By introducing a dielectric layer inside the plasmonics antenna we engineer the absorption and scattering spectrum. Our lithographically defined meta-antennas with various diameters act as receiver and transmitter nano-antennas to outcouple efficiently the photoluminescence of the QDs.
