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.

胶体量子点（QD）是半导体材料的溶液处理的纳米级晶体。它们发出明亮、纯净且可调的光颜色，使其成为下一代显示器、固态照明（SSL）技术和标牌中色中心的绝佳候选者。量子点已经开始作为光激发的颜色增强剂找到商业应用。由于合成QD的成本和它们的毒性，应该寻找替代品，特别是碳量子点（CQD）。碳量子点（CQD）通过自上而下的方法合成，其中石墨粉末或多壁碳纳米管（CNT）暴露于苛刻的物理或化学条件，例如激光烧蚀、电弧放电和电化学方法，或者通过自下而上的方法合成，碳量子点（CQDs）是通过化学合成、热分解、水热、电化学氧化和微波热分解等方法合成的，近年来，由于其独特的荧光、化学稳定性、水溶性和优异的光稳定性等特性，引起了人们的广泛关注。CQD具有这样的特性，在光电子学、生物成像、能量收集和巧妙的传感等方面有着广泛的应用。我建议在显示器、标志和照明的设备制造过程中利用CQD及其特性。
