The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to introduce new materials to the market that generate high intensity THz-frequency light. These materials will meet the growing needs of many current and emerging scanning and sensing applications that are limited by the strength of THz-frequency light sources. The introduction of brighter THz light sources into current and developing scanners will provide enhanced resolution and sensitivity in a broad range of imaging and sensing applications, including in airport scanners, medical imaging devices, and quality control scanners in manufacturing. These results will expand the impact of THz-frequency scanners, which are safe (non-ionizing radiation) and can provide unique information in many scanning, medical imaging, and sensing applications. The project will also train a diverse group of undergraduate, graduate, and postdoctoral researchers in the field of materials development and entrepreneurship.The proposed project involves the scale up of newly discovered organic materials capable of generating high intensity terahertz-frequency light. Scanning and imaging instruments that employ terahertz-frequency light are safer than many common X-ray based scanners yet are often limited by the lack of bright terahertz-light sources. The organic new materials being produced for commercialization in this proposal provide nearly double the THz light output from current commercial sources. The scale up and growth of larger terahertz-generating crystals will meet the growing demands of companies and researchers who are developing new terahertz-based technologies and who require brighter terahertz sources. Organic materials generally have limited lifetimes due to decomposition under ambient conditions. On this project, commercialization of our prototype layered crystal structures will both enhance THz output and minimize crystal damage during terahertz light generation. These more robust sources of terahertz light will enable the use of organic terahertz light sources in scanners and imagers that previously could not employ this technology due to the short lifetime of organic crystals. In combination, the commercialization of these technologies will facilitate rapid growth in the terahertz scanner sector, enabling safer and more sensitive scanning and imaging technologies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI-TT）项目是将新材料引入产生高强度THZ频率光的市场。这些材料将满足许多当前和新兴的扫描和传感应用的不断增长的需求，这些应用受到THZ频率光源强度的限制。将更明亮的THZ光源引入当前和开发的扫描仪中，将在广泛的成像和感应应用中提供增强的分辨率和敏感性，包括在机场扫描仪，医学成像设备以及制造业中的质量控制扫描仪中。这些结果将扩大安全扫描仪的影响，这些扫描仪是安全的（非电离辐射），并可以在许多扫描，医学成像和传感应用中提供独特的信息。该项目还将培训材料开发和企业家领域的多样化的本科，研究生和博士后研究人员。拟议的项目涉及能够产生高强度Terahertz-Frequermencefency Light的新发现的有机材料的规模。采用Terahertz频率光的扫描和成像仪器比许多常见的基于X射线的扫描仪更安全，但通常受到缺乏明亮的Terahertz-Light源来源的限制。该提案中用于商业化的有机新材料几乎是当前商业来源的光产量的两倍。更大的Terahertz生成晶体的规模和增长将满足正在开发新的基于Terahertz的技术并需要更明亮的Terahertz来源的公司和研究人员的需求。由于环境条件下的分解，有机材料通常具有有限的寿命。在这个项目上，我们原型层状结构的商业化既可以增强THZ输出，又可以最大程度地减少Terahertz光生产生的晶体损伤。这些更强大的Terahertz Light的来源将使扫描仪和成像器中的有机Terahertz光源在以前由于有机晶体的寿命短而无法使用该技术。结合起来，这些技术的商业化将促进Terahertz扫描仪领域的快速增长，使更安全，更敏感的扫描和成像技术。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛的评估而被认为值得通过的支持。影响审查标准。
