The future scale-up of novel low cost systems for QLED manufacture, bridging the gap between new research prototypes and low cost mass production tech

胶体量子点是半导体材料的溶液处理纳米晶体。它们发出明亮、纯净且可调的颜色，使其成为下一代显示器、固态照明(SSL)技术和标牌中色彩中心的极佳候选者。量子点已经开始作为光激发颜色增强剂的商业应用。由于合成量子点的成本和毒性，需要寻找一种替代方法，特别是碳量子点。碳量子点的合成方法可以是自上而下的方法，即将石墨粉或多壁碳纳米管暴露在恶劣的物理或化学条件下，如激光烧蚀、弧光放电和电化学法，或者自下而上的方法，即通过所谓的化学合成来合成碳量子点；近年来，碳量子点因其独特的性质而备受关注，尤其是具有吸引人的荧光、化学稳定性、水溶性和优异的光稳定性。CQD具有这样的性质，在光电子学、生物成像、能量收集和巧妙的感知方面有着广泛的应用。我建议在设备制造过程中利用CQD及其特性来显示、标牌和照明。

Colloidal quantum dots (QDs) are solution-processed nanoscale crystals of semiconducting materials. They emit bright, pure, and tuneable colours of light, making them excellent candidates for colour centres in next-generation display, solid-state lighting (SSL) technologies and signage. The QDs have already begun to find commercial applications as optically excited colour enhancers. Due to the cost of synthesizing QDs and their toxicity, an alternative should be sought, specifically Carbon Quantum Dots (CQDs).Carbon Quantum dots (CQDs) are synthesized either through top-down approaches in which graphite powder or multiwalled Carbon Nano Tubes (CNTs) are exposed to harsh physical or chemical conditions, such as laser ablation, arc discharge and electrochemical methods or the bottom-up approach, where CQDs are synthesized through what is known as chemical synthesis; the thermal decomposition, hydrothermal, electrochemical oxidation and microwave pyrolysis.Recently, carbon quantum dots (CQDs) have gained much attention due to their unique characteristics, notably having attractive fluorescence, chemical-stability, water-solubility, and magnificent photo stability properties. CQDs, owning such properties, have found numerous applications in optoelectronics, bio-imaging, energy-harvesting, and ingenious sensing.I propose to utilize CQD and its characteristics within the device making process for the uses of display, signage and lighting.
