Intellectual merit:Thermally-induced degradation is widely recognized as a performance-limiting obstacle to the development of organic light-emitting-diodes (OLEDs) with longer lifetime and higher brightness, two essential requirements for continued commercial development. The work proposed here will tests a newmeans of re-engineering OLEDs for improved thermal performance based on the implementation of a direct, high resolution thermal imaging technique capable of measuring temperature profiles with a fine spatial and thermal resolution across the light-emitting surface of OLEDs.Broader impact:We envision a long-term overall goal of engineering organic and quantum dot photonic devices for improved performance. This proposal will significantly enhance the infrastructure for research and education at Mt Holyoke College, by creating a novel facility for the fabrication of organic and nanoscale optoelectronic devices.

知识价值：热致降解被广泛认为是开发具有更长寿命和更高亮度的有机发光二极管（OLED）的性能限制障碍，这是持续商业开发的两个基本要求。这里提出的工作将测试一种新的手段，重新设计的OLED，以改善热性能的基础上实施的一个直接的，高分辨率的热成像技术，能够测量整个发光表面的OLED的温度分布与精细的空间和热分辨率。更广泛的影响：我们设想了一个长期的总体目标，工程有机和量子点光子器件，以提高性能。该提案将通过创建一个用于制造有机和纳米级光电器件的新设施，大大加强霍利奥克山学院的研究和教育基础设施。
