Quantum Science Ltd (QS) is an award-winning British materials innovation company that focuses on developing, manufacturing, and supplying quantum dots (QDs), nanomaterials and technologies for infrared imaging and sensing markets.QS has developed a proprietary INFIQ(R) technology to manufacture colloidal quantum dot (CQD) materials as greatest potential platforms for next-generation defence, surveillance, machine vision, medical, automotive, consumer electronics, spectroscopy, and infrared imaging applications. QS INFIQ(R) CQD materials have advantages of tuneable optoelectronic properties across a broad spectral bandwidth, solution processability, substrate compatibility and high scalability at low cost. QS is supplying its INFIQ(R) CQD materials to customers who use them for short-wave infrared (SWIR) photodetectors.To provide our customers with the best materials offering the greatest device performance, it is necessary to have a detailed understanding of the effect of organic ligands utilised in the CQD synthesis and residual impurities from ligand exchange process on downstream processes such as ink formulation and device fabrication. Such insights can be obtained via development of direct measurement and characterisation techniques for the CQDs and ink formulations.QS does not have in-house expertise and facilities to solve these measurement problems and propose to collaborate with the scientists from the National Measurement Laboratory (NML) at LGC group who have cutting-edge facilities and specialised expertise. This project aims to develop reliable techniques and direct measurement systems to quantify ligand composition, impurities, and their interaction with of INFIQ(R) CQD. These will provide feedback on the efficiency of ligand exchange processes and ink formulations, and establish tools for material quality control.Overcoming such measurement challenges will improve QS' product competitiveness, advance customers' device performance, increase sales, gain more market share, and open new markets.

量子科学有限公司（QS）是一家屡获殊荣的英国材料创新公司，专注于开发、制造和供应量子点（QD）、纳米材料和红外成像和传感市场技术。QS开发了专有的INFIQ（R）技术，用于制造胶体量子点（CQD）材料，作为下一代国防、监控、机器视觉、医疗、汽车、消费电子、光谱学和红外成像应用。QS INFIQ（R）CQD材料具有可调光电子特性、宽光谱带宽、溶液加工性、衬底兼容性和低成本高扩展性等优势。QS为短波红外（SWIR）光电探测器客户提供INFIQ（R）CQD材料。为了向客户提供具有最佳器件性能的最佳材料，有必要详细了解CQD合成中使用的有机配体以及配体交换过程中残留的杂质对下游工艺（如油墨配方和器件制造）的影响。这些见解可以通过开发CQD和油墨配方的直接测量和表征技术来获得。QS没有内部专业知识和设施来解决这些测量问题，并建议与LGC集团国家测量实验室（NML）的科学家合作，他们拥有尖端的设施和专业知识。该项目旨在开发可靠的技术和直接测量系统，以量化配体组成，杂质及其与INFIQ（R）CQD的相互作用。这些将提供关于配体交换过程和油墨配方的效率的反馈，并建立用于材料质量控制的工具。克服这样的测量挑战将提高QS的产品竞争力，推进客户的设备性能，增加销售，获得更多的市场份额，并打开新的市场。
