In the recent world, there are number of problems related to counterfeit of the different products. There are number of products, which can be easily duplicated by simple processes and the product is accurate and precise. Even the counterfeit of currency is also a main problem in world’s economic. There are number of sectors, which can be effected due to this reason like duplication of electronic products, duplication of food products, duplication of automobile products, duplication of currency, etc. So there are number of anti-counterfeiting technologies available in the market to prevent counterfeit problems. In this paper, it explains to prevent this type of problems with the help of carbon dot based gel formulation, which can be used in different ways. This paper describes the synthesis process and characterization analysis of carbon dot based smart fluorescent security ink to prevent the counterfeit problems. UV-Visspectrophotometer was utilized to differentiate optical properties and fluoroscpectometer was exploited to differentiate fluorescent properties of carbon dots and carbon dot based fluorescent ink. AFM and FTIR were used to analysis the structural properties of carbon dots and carbon dot based fluorescent ink
