Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

Advanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.

Large Faraday Rotation in Liquid Crystals With Embedded Paramagnetic Ions (Cu2+, VO2+) at Room Temperature

Advanced Optical Materials, EarlyView.
Large Faraday rotation at room temperature is observed in thin films of discotic copper (Cu2+: 3d9) and vanadyl (VO2+: 3d1) enaminoketone complexes. The large Verdet constant originates from a high density of paramagnetic centers, metal‐ligand p−d hybridization and π orbitals involved in optical transitions (identified by DFT calculations), as well as ...

Thickness‐Dependent Infrared Emissivity of Ultrathin Freestanding MoSiN Nanocomposite Membranes

Advanced Optical Materials, EarlyView.
ABSTRACT Metals and dielectrics show opposite trends in thickness‐dependent infrared emissivity: metallic films exhibit a rise in emissivity below a critical thickness, while dielectric films show a corresponding decline. For applications demanding both high emissivity and mechanical strength in membranes with nanoscale thickness, combining these ...

Probing Near‐Field EM Fluctuations in Superparamagnetic CoFeB With NV Quantum Dephasometry

Advanced Optical Materials, EarlyView.
We non‐invasively investigate the superparamagnetic spin dynamics of a 1.1 nm CoFeB layer by probing its near‐field EM fluctuations using NV centers‐based quantum dephasometry. Our findings are further supported by theoretical modeling and SQUID‐based magnetization characterization. These results provide critical insight into the magnetization dynamics
