Technical: Future opto-electronic and plasmonic devices will rely on generation and control of light-fields within custom-engineered composite materials and nanostructures. In particular, controlled generation and amplification of light in nanoscale materials is crucial for achieving next generation compact, integratednanophotonic devices. The research program focuses on the fabrication and characterization of dispersion engineered composite metal/polymer nanostructures for practical applications such as novel light emitters and nanoscale plasmon-enhanced organic lasers. The research materials constitute an important step towards achieving increased efficiency, coherent light emitters that are also cost-efficient, processable and scalable. The research project will proceed along two distinct directions. The first effort will address light emission characteristics in composite planar structures comprising semiconducting organic polymers and fractal silver films with tunable dispersive properties. The second task will focus on organic light emitters coherently coupled to ordered metallic meso-structures designed to exhibit a plasmon-induced transparency ? the plasmonic analog to electromagnetically induced transparency. Both tasks will address spatial light emission characteristics, emission enhancement factors and their correlation with the integrated metal nanostructures, spectra of the emitted fields and plasmon-enhanced laser action. Results of this award will lead to (1) new methods for enhancing and controlling light emission in metal/polymer nanocomposites, together with modeling tools and design guidelines for achieving the desired functionalities. (2) New practical architectures for efficient solid state light emitting materials.Non Technical: Nanostructured metallodielectric composite materials hold the potential for greatly impacting modern photonics, with applications to advanced sensing, imaging and novel light emitting devices. The research work will have significant impact on the development of such future technologies. Students participating in this research will acquire expertise in the field of active plasmonic materials. The research is interdisciplinary in nature, allowing students to gain proficiency in materials science as well as classical and quantum optics, and to develop both experimental and modeling skills. An important goal of this project is to train students in the burgeoning field of plasmonics by exposing university students of all levels to research and multi-disciplinary scientific work. At the undergraduate level the aim is to expand avenues for learning by offering a variety of research and mentoring opportunities. At the graduate level the project addresses student involvement in research, as well as participation in a variety of professional development activities. The latter enable pursuing of scientific knowledge and interests in less-traditional ways, such as participation in a departmentally funded student proposal contest, or informal science education and leadership opportunities. Moreover, the PI's commitment to community outreach and participation in coordinated academic activities serve to further integrate scientific research with evolving societal needs for science education.

技术：未来的光电子和等离子体设备将依赖于定制工程复合材料和纳米结构中光场的产生和控制。特别是，纳米材料中受控的光产生和放大对于实现下一代紧凑、集成的纳米光子器件至关重要。该研究计划的重点是用于实际应用的色散工程复合金属/聚合物纳米结构的制备和表征，例如新型发光体和纳米级等离子体增强有机激光器。这些研究材料构成了朝着提高效率的重要一步，实现了具有成本效益、可加工和可扩展的相干光发射器。研究项目将沿着两个截然不同的方向进行。第一项工作将研究由半导体有机聚合物和具有可调色散特性的分形银膜组成的复合平面结构中的发光特性。第二个任务将集中在有机发光体上，有机发光体相干地耦合到有序的金属介观结构，旨在展示等离子体诱导的透明？等离子体激元模拟电磁诱导的透明。这两项任务都将处理空间光发射特性、发射增强因子及其与集成金属纳米结构、发射场的光谱和等离子体增强激光作用的关系。该奖项的结果将导致(1)增强和控制金属/聚合物纳米复合材料中的光发射的新方法，以及实现所需功能的建模工具和设计指南。(2)高效固态发光材料的新实用结构。非技术：纳米结构金属介电复合材料具有极大影响现代光子学的潜力，应用于先进的传感、成像和新型发光器件。这项研究工作将对此类未来技术的发展产生重大影响。参与这项研究的学生将获得活性等离子体材料领域的专业知识。这项研究本质上是跨学科的，使学生能够熟练掌握材料科学以及经典和量子光学，并发展实验和建模技能。该项目的一个重要目标是通过让各级大学生从事研究和多学科的科学工作来培养新兴的等离子体领域的学生。在本科生层面，其目的是通过提供各种研究和指导机会来扩大学习途径。在研究生阶段，该项目解决了学生参与研究以及参与各种专业发展活动的问题。后者使人们能够以非传统的方式追求科学知识和兴趣，例如参加部门资助的学生提案竞赛，或非正式的科学教育和领导机会。此外，国际科学协会致力于社区宣传和参与协调一致的学术活动，这有助于进一步将科学研究与不断变化的社会对科学教育的需求结合起来。
