High‐pressure recrystallization provides a reproducible route to high‐quality CsPbBr3${\rm CsPbBr}_{3}$ thin films. Optimized processing at 300 bar yields smooth, pinhole‐free, single‐phase 3D perovskite layers with tunable thickness, enhanced crystallinity, reduced amplified‐spontaneous‐emission threshold, improved photostability, and phase‐transition

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 ...

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 ...

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...
