Spectrally Encoded Proximity‐Field Nanopatterning
Advanced Optical Materials, EarlyView.Spectrally encoded proximity‐field nanopatterning (SEPN) enables continuous control of the out‐of‐plane periodicity of 3D photonic crystals by tuning the exposure wavelength while maintaining a fixed in‐plane period. This decouples near‐infrared reflectance from visible iridescence and allows fabrication of integrated multipattern devices with ...

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites
Advanced Optical Materials, EarlyView.Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Aerosol Jet Printed Polymer‐Free High Aspect Ratio Quantum Dot Films for Enhanced Color Conversion
Advanced Optical Materials, EarlyView.Polymer‐free quantum dot color conversion layers are aerosol jet printed at high aspect ratio by tuning the aerosol focus ratio to induce in‐flight droplet drying. Contact‐line pinning suppresses lateral spreading, enabling ∼10 µm‐thick films at ∼50 µm widths with blue light leakage below 0.25% and conversion efficiency approaching 18%, demonstrated ...
