Abstract
The objective of this work was comparing the optical performance of hydrothermally and solvothermal synthesized unique florescent carbon quantum dots (FCQDs) from organic material and use it as a fluorescent ink for one of the significant information encryption applications. The goji berry and sucrose were used as a carbon source of experiment. FCQDs obtained by simple hydrothermal and solvothermal methods by using water, isopropanol and acetone as a solvent. The crystal structure and optical properties of the obtained carbon dots are investigated. The obtained all FCQDs are amorphous phases. The maximum emission of the obtained CDs was found at 465 nm when excited at 386 nm. The fluorescent ink potential of the synthesized FCQDs were compared and the best result found at carbon dot that synthesized from solvothermal methods with acetone solution.
