Flexible optoelectronics have fully demonstrated their transformative roles in various fields, but fabrication and application been limited by complex processes. Liquid metals (LMs) are promising to be ideal raw materials for making flexible due extraordinary fluidity printability. Herein, we propose a painting-modifying strategy based on solution processability directly printing out fluorescent from LMs via surface modification. The of eGaIn, which were obtained the mixing gallium with indium metal spheres, used as ink paint high-finesse patterns substrates. Through introducing modification LMs, atom was transformed into composite functional layers GaO(OH) GaN after being modified an ammonia aqueous solution. Owing painting, this is not any curved surfaces, shapes, or facilities has excellent adaptability. Particularly, through spontaneous, instantaneous, solution-processable process that environmentally friendly, easy administrate, recyclable, adjustable. present finding breaks limitations provides strategies addressing severe challenges facing existing optoelectronics. This method expected very useful fabricating lights, transformable displays, intelligent anticounterfeiting devices, skin-inspired optoelectronics, chameleon-biomimetic soft robots coming time.

ABSTRACT To tackle the challenge of non‐destructively analyzing complex oxide layers formed by atmospheric corrosion on active metals, we investigate potential inverse spatially offset Raman spectroscopy (inverse‐SORS) to detect products and elucidate how spectroscopic features SORS vary. This study explores utilization inverse‐SORS technology for longitudinal structural analysis opaque CeO 2 /La O 3 laminates, which serve as a proxy products. Through combination experimental measurements Monte Carlo simulation, it demonstrates feasibility in elucidating layered structure these laminates. With increasing spatial this technology, intensity ratio La ‐to‐CeO increases from 0.23 3.2 then decreases 0.27 sample with 34‐μm‐thick layer under 532‐nm excitation, whereas bottom is hardly detected when thickness upper 225 μm. The results reveal that thinner facilitates escape detection signals originating layer, leading an enhanced signal reduced at characteristic peak. research also sheds light intricate interplay among multiple variables, such offset, laser wavelength, corresponding absorption factor, compactness. These insights suggest valuable non‐destructive approach dissecting structures highly turbid composites metallic compounds semi‐quantitatively deducing their thickness.
