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 ...

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces
Advanced Optical Materials, EarlyView.Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

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 ...
