This Small Businesses Innovation Phase I research project concerns the development of a new class of polymer encapsulation materials with a very high refractive index (exceeding 2.0) and the use of the encapsulant material for light-emitting diodes (LEDs) with high light-extraction efficiency. The proposed effort introduces a new class of nanomaterial-based polymer encapsulants with an unprecedented high refractive index (n 2.0). Such materials would be extremely beneficial for light extraction in light-emitting diodes. Increases of 20 % - 45 % in light extraction efficiency are expected from the employment of the new encapsulant. The intellectual merit also lies in the fundamental assessment of the optical scattering properties of this nanocomposite. The availability of the new encapsulant would be very beneficial to all technical fields employing LEDs including signage, lighting, communications, imaging, biotechnology, and medicine. The development of a new high-index encapsulant would have a tremendous impact on LED technology because virtually all LEDs are packaged and encapsulated. A successful completion of the program could result in a worldwide paradigmatic shift in the packaging and encapsulation of optoelectronic devices. The broad deployment of efficient LED technology for general lighting applications would result in electrical energy savings in the TWh range per year in the United States.

该小型企业创新第一阶段研究项目涉及开发一种具有极高折射率（超过 2.0）的新型聚合物封装材料，以及将该封装材料用于具有高光提取效率的发光二极管 (LED)。这项工作引入了一种新型的基于纳米材料的聚合物封装剂，具有前所未有的高折射率（n 2.0）。这种材料对于发光二极管中的光提取极其有益。使用新型密封剂预计光提取效率将提高 20% - 45%。智力价值还在于对这种纳米复合材料的光学散射特性的基本评估。新型封装剂的出现将对所有采用 LED 的技术领域非常有利，包括标牌、照明、通信、成像、生物技术和医学。新型高折射率封装剂的开发将对 LED 技术产生巨大影响，因为几乎所有 LED 都经过封装和封装。该计划的成功完成可能会导致全球范围内光电器件封装的范式转变。在普通照明应用中广泛部署高效 LED 技术将在美国每年节省 TWh 范围内的电能。
