A spectral compensation strategy is introduced to overcome radical‐induced degradation of dichroic dyes during UV photopolymerization. By incorporating a complementary photochromic liquid‐crystalline dye, broadband optical attenuation is preserved without disrupting photopolymerization, enabling high‐contrast and durable dye‐doped liquid crystal ...

Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals
Ion‐driven electrohydrodynamic effects enable dynamic photonic bandgap modulation in cholesteric liquid crystals under low‐frequency AC driving. By regulating ion‐mediated disturbance of the helical structure, this approach produces two reversible optical responses: rapid color shifting across the visible spectrum and broadband reflection spanning the ...

Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams
Standalone low‐index microscale ridges (MRs) are promising platforms for all‐dielectric structural color generation. They are compact and easy to fabricate, but their color purity trails behind that of resonator‐ or periodic pattern‐based structural color pixels.

Flexible and Scalable 2D/3D Tin‐Based Perovskite Photodetectors via Inkjet Printing
Lead‐free tin‐based perovskite films are successfully fabricated via scalable inkjet printing on rigid and flexible substrates. Incorporating high‐purity precursors and dual‐layer encapsulation minimizes defects and eliminates oxidation. The resulting photodetectors demonstrate high responsivity, persistent photoconductivity, and excellent 30 day ...

The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

Motion was found to induce significant variation in the luminescence intensity ratio of NIR‐emitting Tm3+‐doped NaYbF4 nanoparticles, which has been ascribed to the population dynamics of the Tm3+ ion's excited states. These findings provide the groundwork for the design of motion nanosensors that can operate in environments not accessible with UV–vis ...
