MRI: Acquisition of a Femtosecond Fluorescence Upconversion System

ECCS-0723114 Xingzhong Yan，南达科他州州立大学学术成就：这一主要研究仪器提案为获得飞秒荧光上转换系统提供了理由。 该项目的具体目标是为南达科他州新成立的光敏纳米系统研究和教学集群增加超快光谱能力。这种能力对于研究光致超快能量和电荷转移过程至关重要，这些过程通常发生在光伏材料中的光激发，电荷分离，电子注入和相关现象中。 对这些过程的理解将有助于实现研究集群的目标，即具有成本效益的太阳能电池技术。 此外，该仪器还将用于研究癌症治疗光疗的光敏剂，用于荧光成像和药物输送的量子点，以及用于光学传感器的新荧光共轭系统。 更广泛的影响：该项目将加强南达科他州三个研究机构之间的合作和跨学科研究：南达科他州州立大学、南达科他州大学和南达科他州矿业技术学院&。 该研究集群涉及10多名教师和30多名化学，电气工程和材料工程研究生。 所要求的仪器的可用性将显着提高研究和教学基础设施，并刺激在三个机构的新应用，并支持一个新的电气工程博士学位。南达科他州州立大学的一个项目。 它还将启动飞秒科学和技术的本科生研究活动，并为K-12学生和美洲原住民学生提供机会。 研究成果，新的课程材料，以及与设备开发的教学方法，将在科学界的教学和研究以及当地产业产生广泛的影响。

ECCS-0723114Xingzhong Yan, South Dakota State University Intellectual Merit: This major research instrumentation proposal provides the justification for the acquisition of a Femtosecond Fluorescence Upconversion System. The specific objective of this project is to add ultrafast spectroscopy capabilities to a newly established Photoactive Nanoscale System research and teaching cluster in the State of South Dakota. This capability is critical for investigating photoinduced ultrafast energy and charge transfer processes, which commonly occur in photoexcitation, charge separation, electron injection and related phenomena in photovoltaic materials. The understanding of these processes will help to reach the goal of the research cluster which is cost effective solar cell technologies. Also, the instrumentation will be used for the investigation of photosensitizers for phototherapy for cancer treatment, quantum dots for fluorescence imaging and drug delivery, as well as new fluorescent conjugated systems for optical sensors. Broader Impacts: This project will enhance collaboration and interdisciplinary research between the three research institutions in South Dakota: South Dakota State University, University of South Dakota, and South Dakota School of Mines & Technology. This research cluster involves more than 10 faculty and over 30 graduate students in chemistry, electrical engineering and materials engineering. The availability of the requested instrumentation will significantly enhance the research and teaching infrastructure, and stimulate new applications in the three institutions and support a new electrical engineering Ph.D. program at South Dakota State University. It will also initiate undergraduate research activities in femtosecond science and technology, and provide opportunities for K-12 students and Native American students. Research results, new curricular materials, and pedagogical approaches developed with the equipment, will have a broad impact on both teaching and research in the science community as well as to local industries.
