Unveiling Unconventional Luminescence Behavior of Multicolor Carbon Dots Derived from Phenylenediamine

The Journal of Physical Chemistry Letters, Год журнала: 2023, Номер 14(26), С. 5975 - 5984

Опубликована: Июнь 22, 2023

Fluorescence regulation of carbon dots (CDs) during their preparation has become a hot research topic. In this work, multicolor fluorescent CDs with unconventional luminescence behavior are prepared by using o-, m-, or p-phenylenediamine (o-PD, m-PD, p-PD, respectively) and 2,3-dihydroxynaphthalene rich hydroxyl groups as reaction precursors. Tunable bright blue, yellow, red colors can be obtained solvothermal method under the joint action ethanol hydrochloric acid. The fluorescence emission synthesized follows rule o-PD to m-PD p-PD from blue red, which is contrary most previously reported results (the following an order p-PD). Our reveal that differences in polymerization, surface states, functional groups, graphite N content might main reasons for behavior. addition, these have good applications fields light-emitting diode lighting anticounterfeiting.

Doped Carbon Dots Enable Highly Efficient Multiple‐Color Room Temperature Phosphorescence

Advanced Optical Materials, Год журнала: 2023, Номер 12(7)

Опубликована: Окт. 26, 2023

Abstract Colloidal carbon dots (C‐dots) are considered as promising heavy‐metal‐free materials to achieve room‐temperature phosphorescence (RTP) properties for applications, such photoelectronic devices, information encryption, and bio‐imaging. However, most of the current obtained RTP C‐dots have a short lifetime with relatively low quantum yield (QY). In this work, large‐scale synthesized via vacuum heating approach multiple emissions (blue, green, yellow), long high 1.92 s, QY 34.4% by selecting different types precursors, which is superior reported C‐dots. The atoms doping strong bonding between neighbored promoted contributes excellent properties. As proof‐of‐concept, as‐obtained used optical ink flexible security codes, exhibiting bright shape 1.37 s. This work offers an efficient producing high‐quality C‐dots, can be applied anti‐counterfeiting encryption systems.

Multicolor Afterglow Carbon Dots: Luminescence Regulation, Preparation, and Application

Advanced Functional Materials, Год журнала: 2024, Номер 34(25)

Опубликована: Фев. 6, 2024

Abstract Afterglow materials have attracted much attention owing to their long luminescence lifetimes, large Stokes shifts, and emission without real‐time excitation. Compared with traditional organic afterglow materials, carbon dots (CDs), as a new material, superior properties such easy preparation, low toxicity, cost. The color of CDs can be regulated by external factors excitation wavelength, temperature, time, which is highly significant for expanding the diversified applications make them available biotechnology information applications. This review summarizes research progress multicolor in recent years, including regulation strategies, preparation methods, First, are classified into three strategies: room temperature phosphorescence (RTP), thermally activated delayed fluorescence converted RTP, based on Förster resonance energy transfer, strategies regulating analyzed. Second, methods achieving summarized both matrix‐free matrix‐confined aspects. Then, anticounterfeiting encryption, sensing bioimaging introduced detail. Finally, future challenges opportunities prospected provide ideas controlled design wide application.
