Abstract
With the advancement of infrared modulation technologies, infrared display devices have attracted increasing attention. Previous studies have mainly focused on the response time of infrared display devices and have achieved great success. Nevertheless, owing to the restricted material properties or modulation approaches, the response time of the majority of infrared modulating devices remains trapped at level for a few seconds. In this paper, we fabricated an infrared images display device based on lithium-ion intercalated multilayer graphene (MLG). By changing the lithium-ion content and current value, we had successfully improved its response time from approximately 140,000 ms to around 6 ms.Meanwhile, its absorbance also has significant changes within 0.8–1.8 μm (∼75 %–∼25 %) and 2.5–25 μm (∼45 %–∼2 %). In addition, multi-pixel infrared display unit has been realized on a flexible substrate. The letters "N, U, and C″ were dynamically displayed continuously at 3∗3 pixels by controlling lithium-ions intercalate MLG state. Our work is expected to provide theoretical and technological support for ultrafast flexible dynamic infrared display devices.
期刊介绍:
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
