Absorption enhancement based on interaction between the localized surface plasmon (LSP) and molecular exciton is one of the most important phenomena for the development of high-performance solar devices. In this study, hybrids of plasmonic metal nanoparticles and dye molecules have been developed, which exhibit enhanced absorption at precisely tuned wavelengths in a visible region. The hybrids consist of a porphyrin derivative, which has four absorption peaks (Q-bands) in a range of 500-700 nm, and triangular silver nanoprisms (AgPRs), which are developed by us to exhibit precisely tuned LSP resonance wavelengths. Absorption enhancement over the whole Q-band range is induced by the combined use of three kinds of AgPRs of different aspect ratios. Furthermore, the quantitative evaluation of absorption enhancement based on the LSP-based fluorescence enhancement phenomenon has demonstrated that efficient absorption enhancement can be effected at multiple wavelengths.

结合使用不同纵横比的各向异性银纳米棱镜进行多模等离子激子耦合。

基于局部表面等离子体激元（LSP）和分子激子之间相互作用的吸收增强是开发高性能太阳能器件的最重要现象之一。在这项研究中，已经开发出等离激元金属纳米颗粒和染料分子的杂化物，它们在可见光区域的精确调谐波长处显示出增强的吸收。杂化物由卟啉衍生物和三角银纳米棱镜（AgPRs）组成，卟啉衍生物具有500-700 nm范围内的四个吸收峰（Q波段），由我们开发以显示精确调谐的LSP共振波长。通过组合使用三种不同长宽比的AgPR，可以在整个Q波段范围内增强吸收。此外，
