Tunable Plasmon‐Enhanced Wide‐Angle Terahertz Perfect Absorption via Lorentz Media

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
A planar graphene‐Lorentz‐DBR structure realizes wide‐angle terahertz perfect absorption through a composite phase‐amplitude matching mechanism. The Lorentz dielectric provides dispersive phase compensation and controlled loss, whereas graphene supports dissipative coupling, enabling high absorption up to 80° incidence and multichannel spectral ...

Aerosol Jet Printed Polymer‐Free High Aspect Ratio Quantum Dot Films for Enhanced Color Conversion

Advanced Optical Materials, Volume 14, Issue 24, 25 June 2026.
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 ...
