论文摘要
通过量子张量网络计算，我们研究了放置在等离子纳米结构附近的有机分子所经历的较大percell效应。特别是，我们在两个Ag纳米球的间隙上考虑了一个供体-π桥接者染料。我们的理论方法可以对分子振动和光学纳米腔模式的连续性进行现实描述。我们分析了激子动力学和相应的发射光谱，表明这些幅度并未由最新的简化模型准确地表示。通过将分子偶联与辐射和非辐射等离子模式脱离，我们还将光散发到系统中发生的淬火现象学中。
By means of quantum tensor network calculations, we investigate the large Purcell effect experienced by an organic molecule placed in the vicinity of a plasmonic nanostructure. In particular, we consider a donor-π bridge-acceptor dye at the gap of two Ag nanospheres. Our theoretical approach allows for a realistic description of the continua of both molecular vibrations and optical nanocavity modes. We analyze both the exciton dynamics and the corresponding emission spectrum, showing that these magnitudes are not accurately represented by the simplified models used up to date. By disentangling the molecule coupling to radiative and non-radiative plasmonic modes, we also shed light into the quenching phenomenology taking place in the system.
