“…They emit bright fluorescence with band maxima observed in yellow [135,136], orange [137,138], and red [78,139,140] colors. The near-IR absorbing and emitting nanoparticles were recently obtained [141,142]. Thus, the spectroscopic coverage by these emitters is very broad, similarly to the well-known visible fluorescent proteins [143].…”

“…A primeira banda de absorção, localizada na faixa de 190 -250 nm é atribuída à transição eletrônica π -π * das ligações C = C (domínios sp 2 ). A segunda faixa de absorção (250-400 nm), corresponde à transição eletrônica n -π * das ligações C=O [13,14,15]. Todos os carbon dots sintetizados tiveram o mesmo perfil das bandas de absorção.…”

“…Segundo Sharma et al (2017) [11] esses precursores podem ser derivados de animais, humanos, alimentos e materiais residuais. Em vista disso, devido o limão ser uma das frutas mais consumidas do mundo, tornou-se um dos resíduos mais explorados na síntese verde de C-Dots, onde são utilizadas suas cascas, sucos e extratos [13,14,15,16]. Esses resíduos, têm em sua composição ácido cítrico, ácido ascórbico, vitaminas do complexo B, flavonoides, sais minerais e pequenas concentrações de compostos nitrogenados e substâncias pécticas [17,18].…”

“…Ding et al. have reported bioimaging application of highly fluorescent near‐infrared emitting CDs . Up to now, very few reports are available on the modified CQDs‐based fluorescent probes as sensing system for S 2− ion detection; however, no reports are available on the unmodified CQDs.…”
