论文摘要
有证据表明,在波导耦合的Ag/si3n4/au结构与CDSE/ZNS量子点(QD)发射器中激发的表面等离子体偏振子(SPP)之间的能量交换。 QD分散液涂在AG/SI3N4/AU纳米结构的表面上,表面等离子体共振(SPR)在多层结构的表面上被激发,而QD的光致发光(PL)发射是通过使用固定驱动器泵送Probobepopopy evanescent电场来监测的。我们观察到PL发射波长(对应于4-5 MeV)的较大变化,而伴随的电场引起的淬火(高达50%)发射。在逃生场的影响下,PL发射峰分为两个对应于两个频率(Rabi拆卸)的组件。计算机模拟用于了解应发生狂犬病分裂的条件。
Evidence is presented for energy exchange between surface plasmon polaritons (SPPs) excited in waveguide-coupled Ag/Si3N4/Au structures and CdSe/ZnS quantum dot (QD) emitters. The QD dispersion is coated on the surface of Ag/Si3N4/Au nanostructure, surface plasmon resonance (SPR) is excited on surface of multilayered structure and the photoluminescence (PL) emission by the QDs is monitored as a function of the evanescent electric field by using fixed-detector pump-probe spectroscopy. We observe relatively large shift in the PL emission wavelength (corresponding to 4-5 meV) with accompanying electric field induced quenching (up to 50%) of the emission. Under the influence of the evanescent field, the PL emission peak splits into two components corresponding to two frequencies (Rabi splitting). Computer simulations are used to understand conditions under which Rabi splitting should occur.
