display and power supply have been two essential and independent cornerstones of modern electronics.Here,we report a lithium-plasmon-based low-powered dynamic color display with intrinsic dual functionality（plasmonic display and energy recycling unit） which is a result of the electric-field-driven transformation of nanostructured lithium metals.dynamic color displays are enabled by plasmonic transformation through electrodeposition（electrostripping） of lithium metals during the charging（discharging） process,while the consumed energy for coloring can be retrieved in the inverse process respectively.Energy recycling of lithium metals brings energy consumption down to 0.390 mW cm-2(0.105 mW cm-2) for the active（static） coloration state of a pro of-of-concept display/battery device,which approaches nearly-zero-energy-consumption in the near-100%-energy-efficiency limit of commercial lithium batteries.Combining the subwavelength feature of plasmonics with effective energy recycling,the lithium-plasmon-based dynamic display offers a promising route towards next-generation integrated photonic devices,with the intriguing advantages of low energy consumption,a small footprint and high resolution.

Nano-Micro Letters 2021年第5期13卷 17-33页

Silks have various advantages compared with synthetic polymer fibers,such as sustainability,mechanical properties,luster,as well as air and humidity permeability.However,the functionalization of silks has not yet been fully developed.Functionalization techniques that retain or even improve the sustainability of silk production are required.To this end,a low-cost,effective,and scalable strategy to produce TCSs by integrating yarn-spinning and continuous dip coating technique is developed herein.TCSs with extremely long length(>10 km),high mechanical performance(strength of 443.1 MPa,toughness of 56.0 MJ m−3,comparable with natural cocoon silk),and good interfacial bonding were developed.TCSs can be automatically woven into arbitrary fabrics,which feature super-hydrophobicity as well as rapid and programmable thermochromic responses with good cyclic performance:the response speed reached to one second and remained stable after hundreds of tests.Finally,applications of TCS fabrics in temperature management and dynamic textile displays are demonstrated,confirming their application potential in smart textiles,wearable devices,flexible displays,and human–machine interfaces.Moreover,combination of the fabrication and the demonstrated applications is expected to bridge the gap between lab research and industry and accelerate the commercialization of TCSs.

Color metasurface holograms are powerful and versatile platforms for modulating the amplitude,phase,polarization,and other properties of light at multiple operating wavelengths.However,the current color metasurface holography can only realize static manipulation.In this study,we propose and demonstrate a multiplexing metasurface technique combined with multiwavelength code-division multiplexing(CDM)to realize dynamic manipulation.Multicolor code references are utilized to record information within a single metasurface and increase the information capacity and security for anticracks.A total of 48 monochrome images consisting of pure color characters and multilevel color video frames were reconstructed in dual polarization channels of the birefringent metasurface to exhibit high information density,and a video was displayed via sequential illumination of the corresponding code patterns to verify the ability of dynamic manipulation.Our approach demonstrates significant application potential in optical data storage,optical encryption,multiwavelengthversatile diffractive optical elements,and stimulated emission depletion microscopy.

测试科学与仪器：英文版 2013年第1期4卷 77-82页

作者：周苑苑吕常智高廷辛国治 College of Information and Electrical Engineering Shandong University of Science and Technology

If single chip micro computer controls light-emitting diode(LED),it needs abundant peripheral resources,but in this way,it is not convenient to be expanded,modified and maintained.In order to overcome these shortcomings,field programmable gate array(FPGA)is used to control LED.The hardware design uses low power consumption and high performance device EP1C6Q240C8.Quartus II is the software development environment.There are three modules built under the software development environment:divided clock module,word stock module and LED dot matrix display module,and these independent modules are connected to be a whole system.Finally,32×64 dot matrix display is realized successfully.It is convenient for the customer to adjust the three independent modules according to actual demands and it is easier to realize online updation.
