NontechnicalInteresting phenomena happen when light interacts with materials with nanoscale features. For example, the brilliant colors of butterfly wings arise from nanoscale photonic structures. The emerging field of nanophotonics puts such light-matter interaction to use in applications such as generating clean electrical power and improving the efficiency of chemical reactions. In this project, investigators will design and fabricate tunable hybrid nanostructures based on coherent coupling between optically active molecules and the nanoscale environment. Investigators will combine state-of-art experiment and modeling to explore the complex phenomena associated with light-matter interactions in precisely designed and controlled nanoscale environments. The aim is to achieve precise control of light-matter interactions and thereby enable novel technologies. This collaborative project will be carried out at two HBCUs, Norfolk State University and Jackson State University. The extensive educational component will strengthen the graduate and undergraduate programs in STEM at both institutions via collaboration, student exchange and co-advising. Investigators will involve students from underrepresented minorities in cutting-edge research and thereby enrich their education.TechnicalInteraction of light with the ensembles of molecules that are strongly coupled to surface plasmons excited in metal surfaces and nanostructures gives rise to a host of phenomena which can cause dramatic changes in the optical response at the nanoscale. This collaborative research project involves (i) Experimental studies and modeling of optical properties of hybrid photonic materials involving large ensembles of optically active molecules whose optical properties are defined by their strong coupling to the plasmons excited in the system’s metallic components, (ii) Developing novel designs for hybrid photonic materials with potential applications in light technologies; and (iii) Significantly expanding the research capacity at the participating minority institutions (JSU and NSU) by combining research and educational efforts, including joint seminars, student co-advising, and student exchange. The experimental studies will be performed at NSU Labs while the modeling will be carried out at JSU. The results obtained in the course of proposed research will be disseminated via publications, presentations and patents. The proposed project consists of four distinct tasks which have potential applications in organic photovoltaics, opto-electronic nanocircuitry and signal processing. It is expected that nearly a dozen graduate and undergraduate students will be impacted by the program, directly or indirectly, over a three-year span of the project. The synergy between the research, education and outreach activities planned in this project could profoundly impact the minority students at participating institutions and provide an example of a fruitful collaboration between HBCUs in cutting-edge research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

当光与具有纳米级特征的材料相互作用时，非技术知识现象就会发生。例如，蝴蝶翅膀的鲜艳色彩来自纳米级光子结构。纳米光子学的新兴领域将这种轻度的相互作用用于应用于诸如产生清洁电力和提高化学反应效率之类的应用。在这个项目中，研究人员将根据光学活性分子和纳米级环境之间的相干耦合设计和制造可调式杂种纳米结构。研究人员将结合最先进的实验和建模，以探索精确设计和受控的纳米级环境中与光结合相互作用相关的复杂现象。目的是实现对光 - 物质相互作用的精确控制，从而实现新技术。该协作项目将在两个HBCUS，诺福克州立大学和杰克逊州立大学进行。广泛的教育组成部分将通过合作，学生交流和共同努力来增强STEM中STEM的毕业生和本科课程。调查人员将使来自人为不足的少数群体的学生参与尖端研究，从而丰富他们的教育。通过与分子的结合进行技术互动，这些分子与在金属表面上激发的表面等离子体结合在一起，并在金属表面上激发，纳米结构会导致许多现象，从而导致在Nananspale的光学响应中引起巨大的变化。该协作研究项目涉及（i）（i）混合光子材料的光学性能的实验研究和建模，涉及光学活性分子的大集合，其光学特性是通过其强耦合到系统金属组件中激发的等离子的强耦合来定义的，（II）与潜在材料一起在电脑技术中开发了新型材料设计的新颖材料设计； （iii）通过结合研究和教育工作，包括联合准则，学生共同审议和学生交流，从而大大扩大参与少数民族机构（JSU和NSU）的研究能力。实验研究将在NSU实验室进行，而建模将在JSU进行。在拟议的研究过程中获得的结果将通过出版物，演示和专利传播。所提出的项目由四个不同的任务组成，这些任务在有机光伏，光电动纳米电路和信号处理中具有潜在应用。预计将在该项目的三年范围内直接或间接地受到该计划的影响，将近十几个毕业生和本科生将受到该计划的影响。该项目计划中计划的研究，教育和外展活动之间的协同作用可以深远影响参与机构的少数群体学生，并提供了HBCUS在尖端研究中进行富有成果的合作的例子。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子和更广泛的影响来评估NSF的法定任务，并被视为珍贵的支持。
