Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

Advanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.

Functional Forms for Lorentz Invariant Velocities

Mathematics
Lorentz invariance lies at the very heart of Einstein’s special relativity, and both the energy formula and the relative velocity formula are well-known to be invariant under a Lorentz transformation.

Interactions of Nitrogen‐Vacancy Centers in Diamond with Electron Beams: Implications for Quantum Sensing and Photoluminescence Stability

Advanced Optical Materials, EarlyView.
Under the influence of an electron beam, the photoluminescence (PL) and quantum sensing stability of nitrogen‐vacancy (NV) centers in fluorescent nanodiamonds (FNDs) change. This work elucidates structural and functional changes induced by the electron beam in FNDs and identifies imaging conditions to preserve NV properties and offers a pathway for top‐

Analysis of Electromagnetic Problems in the Presence of Non-uniform Movements [PDF]

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Electromagnetic problems with moving structures are considered. For objects moving at a uniform velocity, the most popular technique used in the literature consists of a change of the reference frame and the utilization of Lorentz transformation of ...

Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

Advanced Optical Materials, EarlyView.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.

Spectrally Adjustable Narrowband Photonic Device Based on Heat‐Driven Amorphous‐to‐Crystal Transformation of Si

Advanced Photonics Research, EarlyView.
The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...

Strain‐Induced Optical and Molecular Transformations in Poly(Ethylene Terephthalate) Films for Organic Electronic Applications

Advanced Photonics Research, EarlyView.
This study explores how mechanical strain affects the optical and molecular properties of poly(ethylene terephthalate) (PET) films, crucial for flexible electronics. Using UV–Vis and Raman spectroscopy, it reveals strain‐induced changes in transparency and vibrational modes. Findings provide insights into optimizing PET‐based devices like organic solar

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons

Advanced Photonics Research, EarlyView.
Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.
