外文标题：Direct Photolithography of WOx Nanoparticles for High-Resolution Non-Emissive Displays

外文摘要：High-resolution non-emissive displays based on elec-trochromic tungsten oxides(WOx)are crucial for future near-eye vir-tual/augmented reality interactions,given their impressive attributes such as high environmental stability,ideal outdoor readability,and low energy consumption.However,the limited intrinsic structure of inorganic materials has presented a significant challenge in achieving precise patterning/pixelation at the micron scale.Here,we successfully developed the direct photolithography for WOx nanoparticles based on in situ photo-induced ligand exchange.This strategy enabled us to achieve ultra-high resolution efficiently(line width＜4 μm,the best resolution for reported inorganic electrochromic materials).Addition-ally,the resulting device exhibited impressive electrochromic performance,such as fast response(＜1 s at 0 V),high coloration efficiency(119.5 cm2 C-1),good optical modulation(55.9％),and durability(＞3600 cycles),as well as promising applications in electronic logos,pixelated displays,flexible electronics,etc.The success and advancements presented here are expected to inspire and accelerate research and development(R&D)in high-resolution non-emissive displays and other ultra-fine micro-electronics.
