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：等离激元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发射速率。然而，为了将等离子体效应纳入基于共轭聚合物的光电器件中，控制和稳定等离子体结构的表面电子特性非常重要。该项目的目标是开发多功能等离子体电极的设计原理，这些原理是：（1）光学活性； (2) 高效的载流子收集/注入； (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制造路线兼容。等离子体电极由垂直取向的金属纳米棒阵列组成，支持表面等离子体，并且没有涂层或具有超薄（天然）金属氧化物涂层，以调整表面功函数，无需额外的空穴传输/电子阻挡层，减轻激子猝灭，并提高环境条件下的性能寿命。非技术描述：该项目中开发的电极提供光管理功能并表现出稳定、可控的表面电子特性，预计将提高效率以及更耐用的有机聚合物光电器件，使其更适合能源效率和发电应用。该项目活动还将材料科学与工程、化学等跨学科研究与教育结合起来，让来自地方和州项目（例如罗格斯大学科学与工程研究项目、罗格斯大学绿色能源技术 REU 项目和新泽西州州长学校）的本科生参与其中。工程与技术学院）与研究生研究人员一起实现该项目的目标。其他项目活动继续支持、鼓励和保持研究团队和更广泛的科学界的多样性；并将参与高中强化活动作为罗格斯大学外展计划的一部分。
