PI: Amos, Delaina Institution: University of LouisvilleIntellectual Merit: The need for innovation in high-efficiency lighting devices has been recognized for some time. Solid-state lighting devices have the potential to increase two- or more fold over the efficiencies of the best conventional lighting technologies available today. Even though there has been significant progress with solid-state device technology based on single crystal semiconductors, there is still a large need for developing such technologies utilizing inexpensive materials and processes. Organic-inorganic composite lighting technology offers such possibilities in terms of both materials and processes; however, the current state-of-the-art technology is limited by low efficiencies. This BRIGE award proposes to develop new materials, processes and fundamental understanding necessary for transformational advances with light emitting diode (LED) devices based on organic-inorganic composite materials. The objective is to develop novel quantum dots (QDs), QD/ligand chemistry and conductive polymers (CP) for use in hybrid organic-inorganic LEDs. Another objective of this project is to investigate the use of inkjet printing and other scalable techniques for the thin film deposition of the multi-layer device. Specifically, the project will focus on the following four directions: (1) synthesis of novel QDs made using earth abundant and less toxic elements; (2) functionalization of QDs and investigation of the QD-CP interface in terms of device performance; (3) use of inkjet deposition to lay down the QD and polymer layers in discrete red, green and blue sections to produce white light; and (4) fabrication and testing of LED devices in terms of energy conversion and light emission efficiency.Broader Impacts: The proposed broadening participation plan includes the following objectives (1) to create and disseminate a traveling history of lighting display with an accompanying video targeted at regional K-12 students; (2) to create a half-day Engineering school-wide undergraduate and graduate research symposium; and (3) to develop curriculum for a new graduate course entitled "Quantum Dots and Lighting." In addition to research and curricular integration outcomes, the PI plans to focus on various activities for increasing graduation and retention rates for underrepresented minorities in the STEM areas. Long-term societal impacts will be to elevate the awareness of renewable energy challenges, goals and emerging lighting technologies at the K-12, undergraduate and graduate levels as well as to increase graduation and retention rates for this target population. Technological impacts will include new scalable processing techniques leading to lower cost LED lighting and significantly improved environmental impact and lighting energy efficiencies relative to traditional lighting.

主要研究者：Amos，Delaina机构：路易斯维尔大学智力优势：高效照明设备创新的必要性早已被认识到。 固态照明设备有可能比当今可用的最佳传统照明技术的效率提高两倍或更多倍。尽管基于单晶半导体的固态器件技术已经取得了重大进展，但仍然存在开发利用廉价材料和工艺的这种技术的巨大需求。有机-无机复合照明技术在材料和工艺方面提供了这种可能性;然而，目前最先进的技术受到低效率的限制。该奖项旨在开发新材料，工艺和基本理解，这些都是基于有机-无机复合材料的发光二极管（LED）器件转型进步所必需的。 目的是开发用于混合有机-无机LED的新型量子点（QD）、QD/配体化学和导电聚合物（CP）。 本项目的另一个目的是研究使用喷墨印刷和其他可扩展的技术用于多层器件的薄膜沉积。具体而言，该项目将集中在以下四个方向：（1）使用地球丰富和毒性较低的元素合成新型量子点;（2）量子点的功能化和QD-CP界面的器件性能研究;（3）使用喷墨沉积法将量子点和聚合物层沉积在离散的红色，绿色和蓝色部分中以产生白光;（4）将量子点和聚合物层沉积在量子点和聚合物层上以产生白色。及（4）LED器件的制造及能源转换和发光效率测试。更广泛的影响：建议的扩大参与计划包括以下目标：（1）制作和传播照明显示器的旅游历史，并以地区K-12学生为对象的视频;（2）设立一个为期半天的工程学院本科生和研究生研讨会;及（3）为一个名为“量子点与照明”的新研究生课程制订课程。“除了研究和课程整合成果外，PI计划重点开展各种活动，以提高STEM领域代表性不足的少数民族的毕业率和保留率。 长期的社会影响将是提高K-12，本科生和研究生水平对可再生能源挑战，目标和新兴照明技术的认识，以及提高这一目标人群的毕业率和保留率。技术影响将包括新的可扩展处理技术，从而降低LED照明的成本，并显着改善环境影响和相对于传统照明的照明能源效率。
