Probing the exotic emission behaviors of Gd3+ ions in Gd3Ga5O12 wafer via X-ray excited optical luminescence

Results in Optics
We investigate the exotic emission behaviors of gadolinium gallium garnet (Gd3Ga5O12, GGG) wafer via X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) in an X-ray nanoprobe beamline. The XANES spectra of the Gd L3

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

Advanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...
