Synthesis of photoluminescent carbon dots and their application in security ink development

Abstract

The study mentioned in the thesis "Synthesis of photoluminescent carbon dots and their application in security ink development" primarily involves two concerns: first, the synthesis of Carbon Dots, and second, the preparation of stable fluorescent ink. Carbon dots (CDs), which are generally small carbon nanoparticles (less than 10 nm in size) with various unique properties, have found wide use in more and more fields during the last few years. Moreover, CDs are environmentally beneficial due to their non-toxic and inert qualities, which have enhanced the interest of academic and industrial researchers alike. The primary objective is to synthesize Carbon Dots using hydrothermal and microwave synthesis processes. Their structural and optical properties have been researched and characterized. The control of its size and form was achieved by adjusting the time and temperature in the preparation parameter. CDs have been thoroughly discussed in all areas, including their prospective uses in fluorescent ink development. The diverse application of Carbon Dots are discussed in this course of work.
