摘要

在这个新兴的科技世界里,由于工业经济的提高,假冒产品越来越多。仿冒和人类创造有价值物品的欲望一样古老。产品数量多,简单工艺即可轻松复制,产品准确、精密。假冒是一个产品安全问题,其兴起并影响到从消费品到药品和备件的每一个产品类别。产品还可能含有非活性甚至有毒成分。因此,发光材料可用于检测不同波长的不同假冒产品。采用碳点-镧系复合基凝胶配方涂覆在不同的减法上,并根据不同的工艺涂覆其不同的表征部位,以防止出现假冒问题。碳点-镧系复合材料基本易于合成,且具有荧光特性,可使产品具有独特性和多样性。在紫外室的帮助下,碳点-镧系复合材料很容易在特定波长下被检测到。因此,利用这一特性,可以制备凝胶配方,以涂覆在不同的减法上,并具有不同的表面形态,以供未来的戒律使用。利用紫外-可见分光光度计对碳点、碳点-镧系复合材料和cd -镧系荧光油墨的光学性能进行了区分,利用荧光光谱仪对碳点、碳点-镧系荧光油墨的荧光性能进行了区分。利用FT-IR和粘度计对碳点-镧系荧光油墨的其他性能进行了表征。本研究是对碳点基智能荧光防伪油墨一步合成的修正文章。

Carbon Dot-Lanthanide Composite Based Smart Luminescent Anticounterfeiting Material
In this emerging technology world, the counterfeit of products are increasing due to raising the economy of industry. Counterfeiting is as old as the human desire to create objects of value. There are number of products, which can be easily duplicated by simple processes and the product is accurate and precise. Counterfeit is a problem of product security, the rise and affects every product category from consumer goods to medicines and spare parts. Products can furthermore contain non-active or even toxic- ingredients. So, luminescent materials are useful to detect different counterfeit products at different wavelength. The carbon dots-lanthanide composite based gel formulation is used to coat on different subtract and according to the process their different characterization part for the prevention of counterfeit problems. Carbon dots-lanthanide composites are basically easy to synthesis and they have fluorescent property, which can help to make product unique and diverse. With help of UV chamber, the carbon dots-lanthanide composites are easily detected at some particular wavelength. So by using this property, the gel formulation can be fabricated to coat on different subtract and characterize different surface morphology for the future precepts. UV-Vis- spectrophotometer was utilized to differentiate optical properties and fluorospectrometer was exploited to differentiate fluorescent properties of carbon dots, carbon dots-lanthanide composite and CDs-lanthanide based fluorescent ink. FT-IR and viscometer were used characterized other properties of carbon dots-lanthanide based fluorescent ink. This research article is the revised article of one step synthesis of carbon dots based smart fluorescent security ink.
