“…The mechanisms of fluorescence quenching are multiple and are related to the interactions between CDs and the quencher molecules. The quenching mechanisms are (i) dynamic quenching [ 81 ], (ii) static quenching [ 82 ], (iii) photoinduced electron transfer [ 83 ], (iv) Förster resonance energy transfer [ 84 ], (v) Dexter energy transfer [ 85 ], (vi) inner filter effect [ 86 ] and surface energy transfer [ 87 ].…”

Carbon quantum dots are the materials of a new era with astonishing properties such as high photoluminescence, chemical tuneability and high biocompatibility. Since their discovery, carbon quantum dots have been described as nanometric high-fluorescent carbon nanoparticles, but this definition has become weaker year after year. Nowadays, the classification and the physical explanation of carbon quantum dots optical properties and their chemical structure remain matter of debate. In this review, we provide a clear discussion on these points, providing a starting point for the rationalization of their classification and a comprehensive view on the optical and chemical features of carbon quantum dots.

“…Song and co-workers reported the synthesis of CNPs for the sensing of oxytetracycline (OTC) via the FRET mechanism. 84 The surface of the blue fluorescent CNPs, covered by amine, carboxyl and hydroxyl groups, interacted with OTC via multiple hydrogen bonds and π–π stacking interactions, reducing their distance to a few nanometers. Thus, the overlap between the absorption spectrum of OTC and the emission spectrum of CNPs occurred, increasing the energy transfer from the CNPs to OTC.…”
