High-performance printable hybrid light-emitting device architectures

一种高性能可打印混合发光器件架构 愿景：这项探索基金的长期目标是开发一项国际公认的研究计划，调查合成和印刷之间的基本相互关系，可印刷光电子是这些快速崛起的领域之一。近年来，开发新的、更好的低成本和可印刷的太阳能光电子平台、照明定位技术得到了极大的推动，这些技术非常适合使用各种基于溶液的材料来生产独特的薄膜结构。这些沉积技术也是结合看似不相容的材料的理想选择，或者在生产混合薄膜异质结构时解决溶剂兼容性问题。 与此同时，令人振奋的新型可打印材料系统在过去5年中也获得了巨大的发展势头，包括用于生产高质量纳米工程金属氧化物材料的新型溶胶-凝胶前驱体、更好的量子点对发射特性的无与伦比的控制以及在混合可打印LED中达到前所未有的器件性能。在接下来的五年里，我们将专注于探索(1)带有和不带有量子点的混合聚合物微滴的组合共喷射，(2)嵌入钙钛矿基质中的碳纳米管金属氧化物(例如二氧化钛)纳米纤维网络，以实现所需的控制，并导致显著改进的器件，这些器件可能会改变可印刷LED和其他用于光收集和传感应用的低成本器件领域。

High-performance printable hybrid light-emitting device architectures Vision: The long-term goal of this Discovery Grant is to develop an internationally-recognized research program investigating the fundamental interrelations between the synthesis printable optoelectronics is one of these rapidly-emerging sectors. In recent years, there was an extraordinary push to develop new and better low-cost and printable optoelectronic platforms for solar-energy harvesting, lighting position techniques, which are well-suited to produce unique film architectures using a wide range of solution-based materials. These deposition techniques are also ideal to combine seemingly incompatible materials, or to address solvent compatibility issues when producing hybrid thin-film heterostructures. Meanwhile, exciting new printable material systems have also gained tremendous momentum in the last 5 years including new sol-gel precursors to produce high-quality nano-engineered metal-oxide materials, better quantum dots ve unparalleled control on the emission properties and reach unprecedented device performance in hybrid printable LEDs. In the next five-year, we will focus on exploring (1) combinatorial co-jetting of hybrid polymer microdroplets with and without quantum dots and (2) carbon nanotube metal-oxide (e.g. TiO2) nanofiber networks embedded within a perovskite matrix to achieve the desired control and lead to significantly-improved devices that can potentially transform the field of printable LEDs and other low-cost devices for light-harvesting and sensing applications.
