Outline of Research at the Start

新規プラズモニックデバイスとして期待される配列した金ナノ微粒子で構成されるメタ表面では局在表面プラズモンの磁気双極子が電気四極子と相互作用し、新しい共鳴モードが励起されることが予想されている。しかし、このような多極子共鳴ピークの観測は重要でありながら、実際上暗く、観測は困難である。本研究では金ナノ微粒子で起こる光第二高調波の散乱(SHレーリー散乱)が金ナノ微粒子の電気四極子に敏感に応答するという原理に着目し、またガラス基板内に一次元配列した金ナノ微粒子の個数や微粒子間隔等を精密に制御することにより、それらによって変調する一次元配列構造の電気四極子共鳴状態をSHレーリー散乱法を用いて解明する。

Outline of Final Research Achievements

In this study, spherical gold nanoparticles were placed in a one-dimensional array structure on a glass substrate, and AFM images of the array showed that the spherical gold nanoparticles were non-uniformly arrayed with a spacing of several tens of nanometers. The spatial distribution of the optical second harmonic (SH) signal was observed to vary with the wavelength of the incident light, and the results of electromagnetic field calculations indicate that this experimental result can be qualitatively explained by the local electric field distribution corresponding to the plasmon resonance frequency. This indicates that SHG microspectroscopy is a sensitive method to observe plasmon modulation in accordance with the fine array structure of one-dimensional gold nanoparticles.

Academic Significance and Societal Importance of the Research Achievements

本研究では光第二高調波発生(SHG)顕微分光法によって、一次元的に配列した金ナノ微粒子の微細な構造の乱れに応じた局在表面プラズモンの変調をサブマイクロンスケールで感度良く観測できる手法であることが示された。この様なSHG顕微法を用いればクローキングデバイスやメタ表面等に応用される基板に埋め込まれ、配列された金ナノ微粒子の微細な構造変化によるプラズモンの変調を感度良く観測することができ、より精密なプラズモンモードの制御を行う為のプローブとして活用されることが期待される。即ち、プラズモニックデバイス開発のための新規観測手法を導入したというところに本研究の社会的な意義がある。
