摘要
2019年新冠疫情席卷全球,给人类社会带来了巨大的影响和经济损失.AlGaN基深紫外发光二极管(DUV-LED)作为新型高效消杀器件,引起了学术界广泛的研究,其中,深紫外透明电极对提升深紫外LED的光电性能至关重要.采用一种新型的高透明度(＞90％)铜基核壳结构金属纳米丝(Cu@metal NSs)电极,实现深紫外LED光输出功率近一倍的提升.基于深紫外LED的阵列排布及配光优化,集成制造了 180 mW深紫外LED消毒灯模组,经生物实验验证,对大肠杆菌及金黄色葡萄球菌的灭活率大于99.99％.更重要的是,高功率消毒器械对新型冠状病毒表现出大于99.9％的灭活性能.本工作有望推动未来新型结构的深紫外发光器件制造及其高效消杀应用.
Abstract
The COVID-19 pandemic since 2019 has brought huge impacts and economic losses to the world.AlGaN-based deep-ultraviolet light emitting diode(DUV-LED)as a new and efficient sterilization device has attracted broad research attentions.The transparent electrode covering deep-UV band plays an important role in improving the performance of deep-UV LEDs.Here,we propose a novel core-shell structure Cu@metal nanosilks(Cu@metal NSs)network electrode with high transparency(＞90％)to enhance the output power of deep-UV LED.In addition,based on the optimized design of integrated array module of deep-UV LEDs,a 180 mW DUV-LED sterilization device is fabricated.The device shows high inactivation performance for Escherichia coli and Staphylococcus aureus(＞99.99％)and for COVID-19 virus(＞99.9％).This work provides a novel method for improving the performance of deep-UV LEDs and pushing forward the efficient sterilization applications.
