Nanoco is the sole UK manufacturer and supplier of state of the art quantum dots (QDs), tiny semiconductor crystals only a few nanometers in size. QDs exhibit unusual and interesting energy efficient properties that are exciting commercially in many fast growing markets including electroluminescent displays, solid state lighting, solar cells, biotechnology and biomedicine. The QDs’ many advantages over conventional devices include higher performance, increased efficiency and significantly lower environmental impact. New markets to exploit their unique properties are close to commercial exploitation.The majority of QDs currently in commercial applications contain cadmium (Cd), a toxicheavy metal which is damaging to the environment. New legislation is preventing/minimising the use of Cd worldwide and Japanese companies will not exploit any Cd-based technology. Of necessity biomedical applications require heavy metal free dots. Nanoco has developed proprietary synthetic routes to produce heavy metal free dots of equivalent performance and stability to Cd-based systems in large quantities. However, some of the precursors currently used are both expensive and inefficient. Nanoco must develop the existing process through the introduction of new and efficient precursors to allow QDs to be commercially viable on industrial scale-up and to compete effectively against existing and emerging technologies.Cost, energy usage and environmental improvements to the process will make theirwidespread use possible in current and new electronic and optoelectronic applications.The synthesis of Cd-free QDs from alternative precursor routes requires detailed investigation and development. In particular new reactor designs will be needed to accommodate the different properties of these new precursors compared to their existing counterparts.The end result of this project would be the late stage prototype of an industrial scalableprocess based on the improved starting materials.

Nanoco是英国唯一的量子点（QD）制造商和供应商，量子点是一种只有几纳米大小的微小半导体晶体。量子点表现出不寻常的和有趣的能源效率的性质，是令人兴奋的商业在许多快速增长的市场，包括电致发光显示器，固态照明，太阳能电池，生物技术和生物医学。量子点与传统器件相比具有许多优势，包括更高的性能、更高的效率和显著降低的环境影响。目前商业应用的大多数量子点都含有镉（Cd），这是一种对环境有害的有毒重金属。新的立法正在防止/最大限度地减少全球镉的使用，日本公司将不会利用任何镉技术。生物医学应用需要不含重金属的点。Nanoco已经开发出专有的合成路线，以大量生产与Cd基系统具有同等性能和稳定性的不含重金属的点。然而，目前使用的一些前体既昂贵又低效。Nanoco必须通过引入新的和有效的前体来发展现有的工艺，以使QD在工业规模上具有商业可行性，并有效地与现有和新兴技术竞争。该方法的能源使用和环境改善将使其在当前和新的电子和光电应用中的广泛使用成为可能。来自替代前体途径的自由QD需要详细的研究和开发。特别是新的反应器设计将需要适应这些新的前体的不同属性相比，他们现有的counterparts.The最终结果，该项目将是后期阶段的原型的工业scalableprocess的基础上改进的起始材料。
