创新的纳米光子应用需要一种技术来产生大面积（mm 2-m2）的近场光源，而不是纳米级的点。我们成功地开发了一种大面积近场光源，该光源由均匀尺寸的金纳米颗粒（AuNPs）以规则的颗粒间间隙二维排列而成，具有可调的局部表面等离子体共振带（600-1100 nm）。基于AuNP二维阵列的光学可调谐性的近场激发特性表明，我们的大面积近场光源的化学涂层可广泛应用于诸如高灵敏度光学传感器和高效率太阳能电池。
Innovative nanophotonic applications require a technique for generating not a nanometer-scale point but a large-area (mm2−m2) near-field light source. We succeeded in developing a large-area near-field light source that is densely constructed of uniform-size gold nanoparticles (AuNPs) two-dimensionally arrayed with regular interparticle gaps, which has tunable localized surface plasmon resonance bands (600–1100 nm). The near-field excitation properties based on the optical tunability of the AuNP two-dimensional arrays demonstrate that our chemical coating of large-area near-field light sources is widely applicable such as for high-sensitivity optical sensors and high-efficiency solar cells.
