Carbon dots-based delayed fluorescent materials: Mechanism, structural regulation and application

Zero-Dimensional Carbon Nanomaterials for Fluorescent Sensing and Imaging

“…Because the number of S 1 →T 1 →S 1 cycles increases with increasing temperature, the temperature is another key TADF parameter. 460 Therefore, fullerenes provide the opportunity for developing temperature-and oxygen-concentration-sensitive fluorescent sensors. 461,462 5.2.2.…”

Evolution and fabrication of carbon dot-based room temperature phosphorescence materials

“…15 These luminescent properties have shown significant application prospects in biomedicine, optoelectronic devices, energy storage, sensing, anti-counterfeiting, catalysis, imaging and other fields. [16][17][18][19] Particularly, the RTP phenomenon of CDs has afterglow emission performance which is very attractive because of its prolonged emission lifetime, larger Stokes shift and minimized interference from short-lived auto-fluorescence and scattered light. Now it has shown a broad application prospect in anti-counterfeiting, information encryption, sensing and other advanced fields.…”

“…Although there are some reviews providing a brief introduction of the afterglow phenomenon ( i.e. , RTP and TADF) of CDs, 15–19,35–38 there are few articles specifically describing the afterglow phenomenon related performance in detail. 39,40 Based on the results previously reported, the radiative transition of triplet excitons is the key factor of the long afterglow phenomenon produced by CDs.…”

Although there are some reviews providing a brief introduction of the aerglow phenomenon (i.e., RTP and TADF) of CDs, [15][16][17][18][19][35][36][37][38] there are few articles specically describing the aerglow phenomenon related performance in detail. 39,40 Based on the results previously reported, the radiative transition of triplet excitons is the key factor of the long aerglow phenomenon produced by CDs.…”

Developing single silane-derived delayed fluorescent carbon dots as donors for energy transfer-based aqueous-phase multicolor afterglow application

“…Since carbon dots (CDs) were discovered in 2004, 19 they have aroused wide attention and become one of the most promising metal-free phosphors due to their advantages, such as being cheap, having easily obtained raw materials and facile preparation, good biocompatibility, high quantum yield, and wide range of emission wavelength regulation. [20][21][22][23][24][25][26] In recent years, afterglow emission of CDs has been achieved by embedding CDs into matrices, such as zeolite, 1,27 SiO 2 , 28,29 boric acid (BA), 30 layered clay, polyvinyl alcohol (PVA), 31,32 and polyurethane (PU). 33 These matrices can effectively stabilize the triplet excited states of CDs to restrain their nonradiative deactivation derived from the vibrations and rotations of molecules, energy transfer, or triplet-triplet annihilation.…”
