One important resource for material synthesis is waste. Utilization of waste as a resource for material synthesis is an environmentally responsible approach that reduces the need for virgin resources and subsequent processing. In this report a method to produce multicolored, luminescent carbon dots (CDs) and subsequent fabrication of light emitting diodes from food, beverage, and combustion wastes, is discussed. Apart from food and beverages, combustion exhaust was also utilized for CDs production. Optical characterization results suggest that CDs from waste food and beverages are more luminescent than those produced from combustion waste.
材料合成的一个重要资源是废物。将废物用作材料合成的资源是一种对环境负责的方法，可减少对原生资源及其后续加工的需求。在本报告中，讨论了一种从食品、饮料和燃烧废物中生产多色发光碳点（CDs）以及随后制造发光二极管的方法。除了食品和饮料外，燃烧废气也被用于碳点的生产。光学表征结果表明，来自废弃食品和饮料的碳点比燃烧废物产生的碳点更具发光性。
