英語, 研究論文(学術雑誌), This study investigates how structural properties influence the hole migration behavior of nickel oxide (NiOx) by evaluating its photoelectrochemical performance. Two fabrication methods were employed for preparing NiOx layers. One is a sol-gel wet process, which allows wide-area coating without the need for specialized equipment. The other is atomic layer deposition (ALD), which enables uniform and conformal coverage on 3D surfaces with the compact oxide layer by leveraging a self-limiting, layer-by-layer growth mechanism. Our findings reveal that both crystallinity and compactness significantly affect the hole transport capability of NiOx layers. We further integrated the NiOx layer as a hole transport layer in an Au-NPs/NiOx/Pt-film photocathode operating under a modal coupling regime. This photocathode exhibited cathodic photocurrent at wavelengths below 800 nm, with a maximum incident photon-to-current efficiency of 0.16% at 600 nm. These results demonstrate that not only the hole injection process but also hole migration properties of the NiOx layer influence the charge separation under modal coupling conditions. - Activation Energy in the Electron Transfer Process and Water Oxidation Intermediate Generation under Plasmon–Nanocavity Strong Coupling

研究論文(学術雑誌), Abstract
Light-sheet fluorescent microscopy has become the leading technique for in vivo imaging in the fields of disease, medicine, and cell biology research. However, designing proper illumination for high image resolution and optical sectioning is challenging. Another issue is geometric constraints arising from the multiple bulky components for illumination and detection. Here, we demonstrate that those issues can be well addressed by integrating nanophotonic meta-lens as the illumination component for LSFM. The meta-lens is composed of 800-nm-thick GaN nanostructures and is designed for a light-sheet well-adapted to biological specimens such as the nematode Caenorhabditis elegans (C. elegans). With the meta-lens, the complexity of the LSFM system is significantly reduced, and it is capable of performing multicolor fluorescent imaging of live C. elegans with cellular resolution. Considering the miniature size and plane geometry of the meta-lens, our system enables a new design for LSFM to acquire in vivo images of biological specimens with high resolution. - Boosting Hydrogen Evolution at Visible Light Wavelengths by Using a Photocathode with Modal Strong Coupling between Plasmons and a Fabry‐Pérot Nanocavity

研究論文(学術雑誌), The optical tweezer is one of the important techniques for contactless manipulation in biological research to control the motion of tiny objects. For three-dimensional (3D) optical manipulation, shaped light beams have been widely used. Typically, spatial light modulators are used for shaping light fields. However, they suffer from bulky size, narrow operational bandwidth, and limitations of incident polarization states. Here, a cubic-phase dielectric metasurface, composed of GaN circular nanopillars, is designed and fabricated to generate a polarization-independent vertically accelerated two-dimensional (2D) Airy beam in the visible region. The distinctive propagation characteristics of a vertically accelerated 2D Airy beam, including non-diffraction, self-acceleration, and self-healing, are experimentally demonstrated. An optical manipulation system equipped with a cubic-phase metasurface is designed to perform 3D manipulation of microscale particles. Due to the high-intensity gradients and the reciprocal propagation trajectory of Airy beams, particles can be laterally shifted and guided along the axial direction. In addition, the performance of optical trapping is quantitatively evaluated by experimentally measured trapping stiffness. Our metasurface has great potential to shape light for compact systems in the field of physics and biological applications. - Varifocal Metalens for Optical Sectioning Fluorescence Microscopy

英語, 研究論文(学術雑誌), Near-field enhancement and dephasing time play critical roles in several applications of localized surface plasmon resonance. Here, using an example gold dimer system, we reveal the correlation between the near-field enhancement and dephasing time via time-resolved photoemission electron microscopy. Compared with isolated particles, dimers with small gap sizes show stronger near-field enhancement and shorter dephasing times. These results are well reproduced by numerical simulations and further explained by a coupled dipole approximation model. The roles of near- and far-field coupling and plasmon localization in balancing near-field enhancement and dephasing time are also unveiled. - Efficient Hot‐Electron Transfer under Modal Strong Coupling Conditions with Sacrificial Electron Donors

In this study, I focused on the dynamics of plasmon-induced electron under the strong coupling conditions. By constructing a Au-NPs/TiO2/Au-film structure with Au-NPs fully inlaid inside the TiO2, the strong coupling between the plasmon resonance of Au-NPs and the cavity resonance is verified to be strongly determined by the electric field in the cavity. Using this coupling strength tunable nanostructures, we studied the electron transfer from Au-NPs to TiO2 as well as the electron-electron, electron-phonon coupling of Au-NPs using transient spectroscopy with a reflection configuration. We found that under the strong coupling conditions, a higher photo-induced electron transfer was observed. In addition, based on the study of electron-electron coupling and electron-phonon coupling of Au-NPs, we found that the electron-electron coupling and/or electron-phonon coupling of Au-NPs were modified under the strong coupling conditions.

本研究では表面増強ラマン散乱計測を利用し、金属ナノ微粒子の表面プラズモン増強水酸化反応を観察した。また、金ナノ粒子を担持した酸化チタン電極におけるプラズモン誘起電荷分離に対する界面効果を明らかにした。さらに、表面プラズモン増強水酸化反応とプラズモン誘起電荷分離に対する界面効果の結果に基づいて、広帯域の光捕集のために金属/半導体/金属によって構成される完全光吸収機能を有するプラズモン誘起光エネルギー変換システムの構築にも成功した。
