This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)The objective of this research is to realize efficient infrared electroluminescence using a hybrid organic-inorganic light-emitting device based on emissive group IV semiconductor nanoparticles including Si, Ge and Si1-xGex.Intellectual Merit: Group IV semiconductor nanoparticles have the potential to be efficient and tunable photon sources in the infrared. To date, these systems have not been extensively studied in light-emitting devices. In this work, performance will be maximized by engineering the device architecture, processing conditions, and nanoparticle passivation length. Device performance will be correlated to nanoparticle film morphology using various microscopies. With an improved understanding of architecture and film morphology for Si-based light-emitting devices, other novel group IV systems will be investigated in order to provide multiple infrared light-emitters. The focus on group IV systems will broaden the study of nanoparticles for photonic device applications, and will also contribute to the basic understanding of radiative and non-radiative processes in these materials.Broader Impact: The PIs have identified as a priority the education of high school, undergraduate and graduate students on issues relating to the synthesis of nanoscale systems and their optoelectronic properties. Programs are proposed including summer research experience for high school students and teachers, research opportunities for undergraduate students through programs at the University of Minnesota, and the integration of research results into undergraduate and graduate classes in Chemical Engineering and Materials Science and Mechanical Engineering. Results will be disseminated to industrial partners through the Industrial Partnership for Research in Interfacial and Materials Engineering, where both PIs are active participants.

该奖项是根据 2009 年美国复苏和再投资法案（公法 111-5）资助的。这项研究的目的是使用基于发射 IV 族半导体纳米颗粒（包括 Si）的混合有机-无机发光器件来实现高效红外电致发光。 、Ge 和 Si1-xGex。智力优点：IV 族半导体纳米颗粒有潜力成为高效且可调谐的红外光子源。迄今为止，这些系统尚未在发光器件中得到广泛研究。在这项工作中，通过设计器件架构、加工条件和纳米粒子钝化长度，可以最大限度地提高性能。使用各种显微镜，器件性能将与纳米颗粒薄膜形态相关。随着对硅基发光器件的结构和薄膜形态的进一步了解，我们将研究其他新颖的 IV 族系统，以提供多种红外光发射器。 对 IV 族系统的关注将拓宽用于光子器件应用的纳米粒子的研究，也将有助于对这些材料中的辐射和非辐射过程的基本理解。 更广泛的影响：PI 已将高等教育确定为优先事项学校、本科生和研究生讨论有关纳米级系统合成及其光电特性的问题。拟议的项目包括为高中生和教师提供暑期研究经验、通过明尼苏达大学的项目为本科生提供研究机会，以及将研究成果整合到化学工程、材料科学和机械工程的本科生和研究生课程中。结果将通过界面和材料工程研究工业合作伙伴关系传播给工业合作伙伴，两位 PI 都是该合作伙伴的积极参与者。
