RADAR: Raman Spectral Analysis Using Deep Learning for Artifact Removal

Advanced Optical Materials, EarlyView.
RADAR is introduced, two lightweight deep learning models for artifact removal, capable of simultaneous denoising and correction of Raman spectra, significantly accelerating high‐quality data acquisition. This work advances Raman spectroscopy as a faster, more reliable tool for chemical analysis, with broad applications in materials science, biomedical

Size Effect on Photothermal Heating Ability of Gold Bipyramids

Advanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

Advanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the

Determining the Width of the Dynamic Emission Zone in Light‐Emitting Electrochemical Cells

Advanced Optical Materials, EarlyView.
The width of the dynamically evolving emission zone (EZ) in light‐emitting electrochemical cells (LECs) is important since it has a strong influence on the emission efficiency. Here, a spectral simulation and measurement method is presented, which is utilized for the determination of the EZ width evolution during the initial operation of a common ...

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

Advanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...
