Equipment for constructing a luminescence characterization setup for organic light emitting devices (OLEDs)

尽管有机发光器件(OLED)技术仍处于起步阶段，但由于其在平板显示器行业中的独特潜力，已迅速吸引了人们的兴趣。从用更明亮、更鲜艳的颜色产生更清晰的图像的能力，到使机械柔性显示器成为现实的独特潜力，OLED相对于其他技术(如液晶显示器和等离子显示器)具有几个关键优势。然而，相对较差的设备稳定性导致设备在运行期间亮度不断降低，这仍然是阻碍更广泛技术商业化的主要挑战。开发更稳定的OLED对于扩大其应用范围和获得这项新技术所提供的独特优势至关重要。在滑铁卢大学，我们正在启动一项研究计划，旨在解决OLED的有限稳定性问题，并实现下一代高稳定器件。我们研究战略的一个独特而基本的组成部分是找出设备故障背后的根本原因，以便分配和有效利用最有效的解决方案。在该方案中，需要用于构建用于测试OLED的光学和光电特性的集成装置的组件。该系统提供了一套独特的测试功能[光谱分布、辐射功率和效率测量、延迟电致发光、时间分辨光致发光]，将用于研究由各种材料和配置制成的OLED的发光特性，以调查和了解器件故障的根本原因，并使更稳定的器件的开发成为可能。这项工作是下一代OLED未来发展的基础，并与加拿大领先的行业合作伙伴合作进行。除了为这些工业合作伙伴提供竞争优势外，这项研究还将为加拿大学生提供培训，让他们获得一种新技术的专业知识，这种新技术有很大潜力在每年数十亿美元的平板显示器行业占据很大份额。

Although still in its infancy, the Organic Light Emitting Devices (OLEDs) technology has rapidly attracted interest because of its unique potential for the flat panel display industry. From their ability to produce sharper images with brighter and more vivid colors to their unique potential to make mechanically flexible displays a reality, OLEDs have several key advantages over other technologies (e.g. liquid crystal displays and plasma displays). However, the relatively poor device stability, which causes a continuous decrease in device brightness during operation, continues to be a major challenge that prevents wider technology commercialization. Developing more stable OLEDs is essential for expanding their applications, and for reaping the unique advantages that the new technology has to offer. At the University of Waterloo, we are launching a research program that aims at addressing the limited stability issue of OLEDs and realizing the next generation of high-stability devices. A unique and fundamental component of our research strategy is to uncover the root causes behind device failure so that the most effective solutions can be assigned and efficiently utilized. In this proposal, components for constructing an integrated setup for testing the optical and optoelectronic properties of OLEDs are requested. The system provides a unique set of testing capabilities [light spectral distribution, radiant power and efficiency measurements, delayed electroluminescence, time-resolved photoluminescence] that will be used to study the light emission properties of OLEDs made of various materials and configurations in order to investigate and understand the root causes of device failure, and to enable the development of more stable devices. The work is foundational to the future development of the next generation of OLEDs, and is pursued in collaboration with leading Canadian industry partners. In addition to providing those industrial partners with a competitive edge, the research will also provide training to Canadian students to acquire expertise in a novel technology that has a strong potential to have a big share in the multi-billion $/year flat panel display industry.
