Energy‐Efficient Synthesis of Multicolor Carbon Dots: Revealing the Role of Core Size and Surface States on Photoluminescence and Electrochemiluminescence for Anticounterfeiting

Advanced Optical Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract Carbon dots (CDs) hold immense potential for various optical applications, however, the economical and mild preparation of multicolor carbon (MCDs) remains challenging, correlation between their photoluminescence (PL) electrochemiluminescence (ECL) is still unclear. In this study, five MCDs with emissions from blue to red are rapidly synthesized using a one‐step ion liquid‐assisted wet chemical method under atmospheric pressure, 1‐butyl‐3‐methylimidazolium chloride ([Bmim]Cl) as reaction medium. The resulting exhibit sizes ranging 1.81 3.15 nm, featuring similar surface structures. models used investigate how core size state determine PL ECL. It found that primarily arises excitation emission within core, whereas ECL governed by states. Notably, all near‐infrared ≈760 which red‐shifted relative independent particle size. Leveraging tunable luminescence, pH‐ solvent‐dependent properties, screen‐printing compatibility, luminescent tracers developed anticounterfeiting freshness indicators. This study advances synthesis full‐color CDs offers valuable insights into modulation expanding applications.
