基于钌配合物自组装微晶的薄膜及发光成像器件制备
Fabrication of Thin Films and Luminescent Imaging Devices Based on Self-Assembled Microcrystals of Ruthenium Complex
摘要
Abstract
Ruthenium complexes exhibit considerable potential for application in devices owing to their high photoluminescence quantum yields and tunable emission wavelengths.Nevertheless,traditional solution-processing methods often lead to disordered molecular aggregation,which detrimentally affects both luminescence efficiency and material stability.Conventional vacuum deposition methods involve complicated procedures and high production costs,which hinder the practical utilization and broader adoption of these materials and devices.To address these challenges,this work presents a novel approach for fabricating tris(bipyridine)ruthenium(Ⅱ)complex microcrystalline films.By employing a mixed-solvent approach,the ruthenium complex is guided to self-assemble on the surface of conductive glass,leading to the formation of microcrystalline architectures.Utilizing gallium-indium(Ga-In)alloy as the counter electrode,a simple device capable of high-intensity visible emission was successfully fabricated.Furthermore,patterned electrodes were prepared using molds and liquid metal.Combining these electrodes with the ruthenium complex microcrystalline films enabled the fabrication of devices capable of emitting patterned light.This study offers a promising pathway for the low-cost and large-area manufacturing of ruthenium-based light-emitting devices.关键词
