Electrochromic (EC) technology can adjust optical properties under electrical stimulation with broad applications in smart windows, displays, and camouflage. However, significant challenges remain developing inorganic EC films high durability, rapid response, mechanical flexibility due to intrinsic brittleness dense microstructure. Herein, a nanostructured quasiplanar heterointerface (Q-PHI) is first introduced into the electrode/EC interlayer realize robust, ultrafast switching tungsten trioxide (WO3) film. The 200 nm-thick Q-PHI WO3 film exhibits remarkable performance, including large contrast (81.8% 83.4% at 700 1500 nm), of 2.4 1.8 s, excellent stability (10,000 cycles 21.3% optical-contrast loss). A large-area (20 × 15 cm2) flexible window also successfully achieved. mechanism lies intense built-in electric field strong interfacial bonding induced by unique longitudinal gradient distribution, greatly enhancing electron/ion transport kinetics, surface ion adsorption, durability.

Опубликована: Янв. 10, 2025

Abstract Quantum size effects and interfacial dimensional interactions enable nanometer‐scale hierarchical heterostructures to adjust band structures by energy level discretization, impurity formation, inversion, allowing for controlled carrier localization directional relaxation. These unique characteristics show great potential applications in ferroelectrics, optoelectronics, capacitors, sensors. Yet, optimizing performance fine‐tuning the properties of nanoscale systems, especially composition, remains a considerable challenge. Here dimensionally confined synthesis is reported through pyrolysis‐based metal‐organic framework‐on‐metal‐organic framework (MOF‐on‐MOF) strategy, resulting continuous metal‐carbon carbon‐oxide interfaces below 50 nm. Off‐axis electron holography theoretical calculations are utilized visualize dynamic conversion between localized free electrons, as well relaxation processes high‐density magnetic coupling at nanoscale. phenomena rarely observed micron‐scale or non‐hierarchical heterostructures. improvements lead significantly enhanced dielectric properties, efficient interaction with high‐frequency electromagnetic (EM) fields, indicated loss bandwidth covering full C‐band.
