Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(25)

Published: Feb. 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.

Direct in Situ Fabrication of Multicolor Afterglow Carbon Dot Patterns with Transparent and Traceless Features via Laser Direct Writing

Nano Letters, Journal Year: 2024, Volume and Issue: 24(10), P. 3028 - 3035

Published: Feb. 27, 2024

Multicolor afterglow patterns with transparent and traceless features are important for the exploration of new functionalities applications. Herein, we report a direct in situ patterning technique fabricating carbon dots (CDs) based on laser writing (LDW) first time. We explore facile step-scanning method that reduces heat-affected zone avoids uneven heating, thus producing fine-resolution CD pattern minimum line width 80 μm. Unlike previous LDW-induced luminescence patterns, patterned films transparent, which is mainly attributed to uniform heat distribution gentle temperature rise process. Interestingly, by regulating parameters precursors, an increased carbonization oxidation degree CDs could be obtained, enabling time-dependent, tunable colors from blue red. In addition, demonstrate their potential applications fabrication flexible stretchable optoelectronics.
