Elucidating the Mechanism behind the Enhancement of Persistent Luminescence in ZnGa2O4: Cr3+ Nanoparticles upon H2O2 Exposure

Advanced Optical Materials, EarlyView.
ABSTRACT Persistent luminescence (PersL) materials exhibit prolonged emission of light, lasting from seconds to hours after stopping the excitation. At the nanoscale, they have attracted considerable interest for applications in in vivo imaging, photodynamic therapy, and biosensing.

Kovacs-like memory effect mediated fiber Bragg grating: resembling a silica quipu

Nature Communications
In antiquity, civilizations employed stone carvings and knotted quipu cords for information preservation. Modern telecommunications rely on optical fibers - silica glass strands engineered for light transmission - yet their capacity as archival media ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Design and numerical analysis of a gap-compensated low loss hollow-core antiresonant fiber with nested elliptical tubes

Scientific Reports
In this research, we propose a novel hollow-core anti-resonant fiber structure designed to enhance light confinement and reduce losses. Our simulation results indicate that the LP01 mode loss is reduced to 1.807 × 10⁻⁶ dB/km at a wavelength of 1.52 μm ...

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons

Advanced Optical Materials, EarlyView.
Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Ultra‐Durable Information‐Encoded Anti‐Counterfeiting Self‐Assembled Nanocrystal Labels

Advanced Optical Materials, EarlyView.
Ultra‐durable cost‐effective information‐encoded anti‐counterfeiting labels are fabricated to secure semiconductor chips. A novel method is used to self‐assemble colloidal quantum wells (CQWs) into color bars. Information can be encoded spatially, spectrally, and opto‐spatially.
