Design of a Synthetic Strategy to Achieve Enhanced Fluorescent Carbon Dots with Sulfur and Nitrogen Codoping and Its Multifunctional Applications

Small, Год журнала: 2023, Номер 19(42)

Опубликована: Июнь 17, 2023

Here, a rational strategy to achieve multifunctional N, S codoped carbon dots (N, S-CDs) is reported, aiming improve the photoluminescence quantum yields (PLQYs) of CDs. The synthesized S-CDs have excellent stability and emission properties independent excitation wavelength. Through introduction element doping, fluorescence CDs red-shifted from 430 545 nm, corresponding PLQYs can be greatly enhanced 11.2% 65.1%. It found that doping elements causes an increase in size elevated graphite N content, which may key factors cause redshift emission. Furthermore, also serves suppress nonradiative transitions, responsible for PLQYs. Besides, certain solvent effect applied detect water content organic solvents, strong sensitivity alkaline environment. More importantly, used "on-off-on" dual detection mode between Zr4+ NO2- . In addition, combinedwith polyvinylpyrrolidone (PVP) utilized as fluorescent inks anti-counterfeiting applications.

Double Emissions in Boron-Doped Carbon Dots for Anticounterfeiting Applications

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(2), С. 2304 - 2311

Опубликована: Янв. 5, 2024

Carbon dots (C-dots) have excellent optical properties and serve as building blocks for various potential applications. However, the origin of double emission in C-dots is still unclear. It highly desirable to understand deeply exciton dynamics double-emission on picosecond time scale. Herein, first time, boron-doped carbon (B–C-dots) are synthesized with a quantum yield high 41.1%. The B–C-dots an excitation-dependent photoluminescent spectrum. Compared one dominant energy state undoped C-dots, exhibited multiple states, proved by femtosecond transient absorption spectroscopy. controllable emissions advance design high-level anticounterfeiting code. As proof-of-concept, combination single-emission we produced bright photoluminescence code, showing great systems.
