Recent developments in nanotechnology have opened new possibilities for the harvesting and emission of light, and transforming its energy to clean electrical power and chemical reactions. This project is aimed at better understanding the fundamental effects and new opportunities associated with emission and transfer of light energy in ensembles of molecules that are strongly coupled to specially designed nanoscale environments. Coupling of the molecules with the nanoscale environment is expected to provide for unprecedented control of light-matter interactions and improvement in the efficiency of light technologies. The project educational component aims at strengthening the graduate and undergraduate programs in STEM disciplines at two Historically Black Universities (HBCUs) Norfolk State University and Jackson State University via collaboration and student exchange. It is designed to enrich education and training of graduate and undergraduate students from traditionally underrepresented minority groups by involving them in cutting-edge research in nanophotonics. Strong coupling of ensembles of quantum emitters (e.g. dye-doped polymers) with plasmonic structures can cause dramatic changes in the media's optical response and physical properties. The effect of the strong coupling on the spontaneous emission, Forster energy transfer, and material's nonlinearity, are of fundamental and practical importance and are the subject of unsettled debates. Potential applications of strongly coupled hybridized photonic materials can range from light harvesting and nanocircuitry operating at optical frequencies to pulse-shaping and directional emission sources. The proposed effort is aimed at (i) Transformative research of hybrid photonic materials, whose optical properties are modified by strong coupling of metallic (plasmonic) and dielectric components with optically active dopants; (ii) Development of new concepts and designs employing hybridized strongly coupled materials and components for new technologies; and (iii) Expanding the research capacity at minority institutions through enhancement of education and outreach programs. The knowledge gained in the proposed research program will be transferred to a broad community of scientists and engineers via publications, presentations and patents. It has a potential to transform, among others, organic photovoltaics, opto-electronic nanocircuitry and signal. Over a three-year span of the project, nearly a dozen graduate and undergraduate students will be impacted by the program, directly or indirectly. Based on the demographics of Norfolk State University and Jackson State University, more than 60% of undergraduate students will be from minority groups traditionally underrepresented in STEM disciplines and more than 50% of all students will be females. The research synergistic with education and outreach activities planned in this project would profoundly impact minority students at participating institutions and provide an example of a partnership 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.

纳米技术的最新发展为光的收集和发射以及将其能量转化为清洁的电力和化学反应开辟了新的可能性。该项目旨在更好地理解与光能发射和转移相关的基本效应和新机会，这些光能发射和转移与特别设计的纳米级环境强耦合的分子集合有关。分子与纳米级环境的耦合有望提供对光-物质相互作用的前所未有的控制和光技术效率的提高。该项目的教育部分旨在通过合作和学生交流，加强两所传统黑人大学（HBCUs）诺福克州立大学和杰克逊州立大学STEM学科的研究生和本科课程。它旨在通过让传统上代表性不足的少数群体参与纳米光子学的前沿研究，丰富研究生和本科生的教育和培训。量子发射体（如染料掺杂聚合物）与等离子体结构的强耦合可以引起介质光学响应和物理性质的巨大变化。强耦合对自发发射、福斯特能量转移和材料非线性的影响具有重要的基础和实际意义，是尚未解决的争论主题。强耦合杂化光子材料的潜在应用范围从光收集和光频率下的纳米电路到脉冲整形和定向发射源。提议的努力旨在(i)混合光子材料的变革性研究，其光学特性通过金属（等离子体）和介电成分与光学活性掺杂剂的强耦合而改变；发展新概念和设计，采用混合的强耦合材料和新技术部件；（三）通过加强教育和外展计划，扩大少数民族机构的研究能力。在拟议的研究计划中获得的知识将通过出版物，演讲和专利转移到广泛的科学家和工程师社区。它在有机光电、光电纳米电路和信号等方面具有转化的潜力。在为期三年的项目中，近12名研究生和本科生将直接或间接地受到该项目的影响。根据诺福克州立大学和杰克逊州立大学的人口统计数据，超过60%的本科生将来自传统上在STEM学科中代表性不足的少数群体，超过50%的学生将是女性。该项目中计划的研究与教育和推广活动的协同效应将对参与机构的少数民族学生产生深远影响，并为hbcu在前沿研究方面的合作提供一个例子。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
