Tunability of optical performance is one of the key technologies for adaptive optoelectronic applications,such as camouflage clothing, displays, and infrared shielding. High-precision spectral tunability is of great importance for some special applications with on-demand adaptability but remains challenging. Here we demonstrate a galvanostatic control strategy to achieve this goal, relying on the finding of the quantitative correlation between optical properties and electrochemical reactions within materials. An electrochromic electro-optical efficiency index is established to optically fingerprint and precisely identify electrochemical redox reactions in the electrochromic device. Consequently, the charge-transfer process during galvanostatic electrochemical reaction can be quantitatively regulated, permitting precise control over the final optical performance and on-demand adaptability of electrochromic devices as evidenced by an ultralow deviation of <3.0%. These findings not only provide opportunities for future adaptive optoelectronic applications with strict demand on precise spectral tunability but also will promote in situ quantitative research in a wide range of spectroelectrochemistry, electrochemical energy storage, electrocatalysis, and material chemistry.

电致变色是一个典型的多学科交叉研究领域:涉及有机与无机材料、物理与化学、电子与光学器件、测试控制及封装技术、太阳能辐射光谱调控与节能、显色与热控等诸多基础和应用研究。近年来,电致变色研究呈现百花齐放、精彩纷呈的复兴态势,特别是在中国的科研技术人员快速进入这一研究领域之后,使得多年稍显沉寂的国际电致变色研究领域浮现出勃勃生机。这一形势大致从国际国内电致变色专业学术会议参会人员的规模数量上可见一斑。两年一度的国际电致变色会议(International Meeting on Electrochomism-IME)已经举办到第13届,最近连续几届参会人数基本维持在150人左右。而国内两年一度的全国电致变色会议(Chinese Meeting on Electrochromism-CME),参会人数由第1届的26人、第2届的150人、第3届的178人、快速增加到2019年第4届的352人。中国的学术界和产业界都对电致变色科学产生了浓厚的兴趣,每次国内电致变色学术会议的参会人员大致维持在学术科研人员1/3、研究生1/3、企业界人员1/3的比例。

Mo thin films were prepared by Mid-Frequency twin target magnetron sputtering as the high reflectivity coating in high temperature solar selective coating. The structure and optical properties of the coatings were studied by X-ray diffraction, scanning electron microscopy and Fourier Transform Infrared Spectrometer and spectrophotometer, the optical constants were inversely calculated by Handley equation. The highest infrared reflectivity of 94% reached at the bias voltage of-150 V and sputtering current 12A of the Mo cathode source, which satisfy the requirement for low thermal emittance solar selective coating applications. The thin films with body centered cubic structure grew along the （110） surface as column crystal, optical constants of Mo thin film were similar with bulk Mo. The thermal emittance of the infrared high reflectance Mo based selective absorber coating can control in 0.15 （400℃）.

采用旋铸急冷工艺在大气环境中制备出了Co77.5Si13.5B9非晶合金带材。X射线衍射(XRD)和透射电镜(TEM)分析表明样品为完全非晶。用差热分析仪测量了非晶薄带的热稳定性参数Tg,Txi,Tpi,加热速度分别为5,10,15,35,55,75,95 ***-1。分析了合金的非等温晶化动力学行为,计算了两个析晶峰的晶化表观激活能。研究发现:不同升温速率的DTA曲线表明非晶合金的晶化过程为两步晶化,在连续加热条件下,随升温速率的加快,Co77.5Si13.5B9非晶合金的特征温度Tg,Txi,Tpi均向高温区移动,说明其玻璃转变和晶化行为均有动力学效应。当分别采用晶化开始温度和两个峰值温度时,所得非晶合金的激活能并不是一稳定值。Ozawa方法计算出的激活能值与Kissinger法计算出的结果是一致的。非晶态Co77.5Si13.5B9合金的晶化百分比与退火温度和退火时间的关系曲线均呈S型曲线,随加热速度的增加,非晶合金的晶化百分比与温度的关系曲线向高温处移动,晶化百分比与时间的关系曲线则向时间缩短的方向移动。

氨气和氮气气氛下热处理对ITO薄膜光电性能的影响

中国材料大会2012

Nowadays, high performance p-type transparent conductive oxide （TCO） thin films have gained tremendous intersts, and the fact is that if p-type TCOs with high electrical conductivity and optical transmittance can be fabricated, transparent p-n junctions can be obtained and invisible electronics be realized, and hence the use area of TCOs will be highly broadened. A lot of work have been done on non-stoichiometric and doped versions of p-type TCOs in the last few years to improve the optical and electrical properties by various deposition techniques. ZnO-based thin films were thought to be the most promising candidate for p-type TCOs based on the fact that ZnO has advantages over the others, so in this paper the development of ZnO-based p-type TCOs has been discussed. Firstly, the reasons why p-type ZnO-based TCOs are difficult to synthesize were discussed, and then the general ways now used to produce p-type ZnO-based TCOs were summerized, including intrinsic p-type ZnO, doping of groupⅠelements, codoping of Ⅴand Ⅲ elements, doping of group Ⅴelements, the origin of p-type conductivity and the feasibility of each way, and the state-of-the-art optical and electrical properties were presented. Finally, the specific shortcomings in producing high quality p-type TCOs were discussed. Based on the comparision, it is believed that the doping of groupⅠelements in ZnO may be the most pronising way in realizing p-type TCO.
