U.S.-Argentina Cooperative Research: New Families of Electrochromic and Photoelectrochromic Thin Films

9802775 Rajeshwar这一美洲计划奖项将资助Krishnan Rajeshwar博士、Norma de Tacconi博士、德克萨斯大学阿灵顿分校(UTA)和R.O.伦扎博士以及阿根廷国立拉普拉塔大学Fisicoquimicas Teoricas y Aplicadas研究所(INIFTA)的一组研究人员开展的为期三年的合作研究项目，以开发和表征新的电致变色(EC)和光电变色(PEC)薄膜家族。这些薄膜会在电脉冲或电化学脉冲的作用下改变其光吸收或反射率。将特别注意实验变量的优化，以使这些新一代装置具有良好的可逆性、快速的时间响应和长期的稳定性。与颜色变化相关的机制方面将通过电子和振动光谱以及传统的电化学和光电化学技术进行现场监测。这种涂层有许多潜在的应用，包括智能窗户、显示器和镜子。这项研究得益于合作者的互补专业知识，以及两个机构的设施。电化学-光电化学石英晶体微量分析方法将在UTA进行，而光谱分析方法将在INIFTA进行。

9802775RajeshwarThis Americas Program award will fund a three-year cooperative research project between Drs Krishnan Rajeshwar and Norma de Tacconi, University of Texas, Arlington (UTA), and Dr. R. O. Lenza, and a group of researchers from the Instituto de Investigaciones Fisicoquimicas Teoricas y Aplicadas (INIFTA), Universidad Nacional de La Plata, Argentina, to develop and characterize new families of electrochromic (EC) and photoelectrochromic (PEC) thin films. These are thin films that change their optical absorbance or reflectance in response to an electrical or electrochemical impulse. Particular attention will be paid to the optimization of experimental variables to bring about good reversibility, fast time response and long-term stability to these new generation devices. The mechanistics aspects associated with the color changes will be monitored in situ by electronic and vibrational spectroscopies as well as by conventional electrochemical and photoelectrochemical techniques. The coatings have many potential applications including smart windows, displays, and mirrors.The research profits from the complementary expertise of the collaborators, as well as by the facilities at both institutions. The electrochemical-photoelectrochemical quartz crystal microgavimetry methods will be done at UTA, while the spectroscopic methods will take place at INIFTA.***
