Technical Description: Plasmonic near-fields can be used to increase exciton generation or emission rate in organic conjugated polymer semiconductor materials. However, to incorporate plasmonic effects in conjugated polymer-based optoelectronic devices, it is important to control and stabilize the surface electronic properties of the plasmonic structure. The goal of this project is to develop design principles for multifunctional plasmonic electrodes that are: (1) optically active; (2) efficient at charge carrier collection/injection; (3) stable under ambient conditions; and (4) compatible with scalable nanofabrication routes for organic polymer optoelectronic applications. The plasmonic electrodes consist of vertically-oriented metal nanorod arrays that support surface plasmons and that are either uncoated or have an ultra-thin (native) metal oxide coating to tune the surface work function, eliminate the need for additional hole transport/electron blocking layers, mitigate exciton quenching, and improve performance lifetime in ambient conditions.Non-technical Description: The electrodes developed in this project, that provide light management capabilities and that exhibit stable, controllable surface electronic properties, are expected to enable both more efficient and more durable organic polymer-based optoelectronic devices, making them more viable for energy efficiency and generation applications. The project activities also combine interdisciplinary research in materials science and engineering, and chemistry with education by enabling undergraduate students from local and state programs (such as Rutgers Research in Science and Engineering program, Rutgers' Green Energy Technology REU program and the New Jersey Governor's School of Engineering and Technology) to work alongside graduate researchers on the goals of the project. Additional project activities continue to support, encourage and maintain diversity in the research team and in the broader scientific community; and incorporate participation in high-school enrichment as part of Rutgers' outreach programs.

技术描述：血浆近场可用于增加有机共轭聚合物半导体材料中激子的产生或排放率。然而，为了将等离子体效应纳入共轭聚合物的光电设备中，控制和稳定等离激元结构的表面电子特性非常重要。该项目的目的是为多功能等离子电极制定设计原理：（1）光学活动； （2）在电荷载体收集/注入时有效； （3）在环境条件下稳定； （4）与有机聚合物光电应用的可扩展纳米化途径兼容。等离子电极由垂直面向的金属纳米棒阵列组成，这些纳米纳米棒阵列支持表面等离子体，它们要么是未涂层的，要么具有超薄（天然）金属氧化物涂层以调整表面功能，从而消除了对额外的孔传输/电子阻滞层的需求，从而减轻了启动的启动性能，并提高了这种投射的影响。能力和表现出稳定，可控的表面电子性能，有望使基于有机聚合物的光电子设备更加有效，更耐用，使其对能源效率和发电应用更具可行性。该项目活动还结合了材料科学和工程学中的跨学科研究，并通过使本地和州计划的本科生（例如Rutgers科学和工程计划的研究，Rutgers的Rutgers'S Green Energy Technology REU计划和新泽西州州州州州长工程学和技术学院）与研究员一起研究项目的研究员。其他项目活动继续支持，鼓励和维持研究团队和更广泛的科学界的多样性；并将参与高中充实的参与作为罗格斯外展计划的一部分。
