“…A broad peak in the range from 3600 to 3100 cm -1 is suggested as the overlap peaks of amine (-NH 2 , -NH-) and hydroxyl (-OH) groups stretching vibrations and the former is considered primarily derived from PLL [17,18]. In particular, two peaks at about 1665 and 1595 cm À 1 correspond to the amide groups of PLL [19], these amide bands appear from the stretching and bending vibrations of the N-H bond [18,20], and the stretching vibrations of the C ¼O and C-N bonds of the amide groups in the PLL [21,22]. The peak at 1405 cm -1 can be assigned to the stretching vibration of the -COO-bond [17,23,24].…”

“…In other words, the CDs should be layer like in morphology. After that, some other research groups used similar methods synthesized CDs from other kinds of soot, such as candle soot [40], natural gas soot and plant soot [41,42]. The obtained CDs also exhibited similar morphologic and PL characteristics with those synthesized from candle soot.…”

Carbon based dots (CDs) composed of sp 2 carbon structures and surface functional groups are a new kind of carbon nanomaterials, exhibiting unique luminescent properties due to the quantum confinement and edge effects. This chapter introduces CDs in detail from their synthetic strategies, morphological and structural characteristics, luminescent properties and mechanisms, and sensing applications. The synthesis methods are summarized as "top-down" and "bottomup" approaches. Luminescent properties discussed include photoluminescence, upconversion luminescence, chemiluminescence, electrochemiluminescence. Sensing applications mainly refer to the chemical and biological sensors based on the luminescent properties of CDs. This chapter provides an overview of the research field and gives future perspectives for developing the exciting materials.

“…Alternatively, the heteroatoms are incorporated to the nanoparticles directly from the starting materials; N-doped aC-dots are derived from soy milk 37 or plant soot. 47 The N-doped gC-dots derived electrolytically from graphite using tetrabutylammonium perchlorate in acetonitrile as the electrolyte 63 exhibit signifi cant electrocatalytic activity against the oxygen reduction reaction (ORR). The PL signal of gC-dots with 7% N content derived hydrothermally by strawberry juice 38 is quenched in the presence of Hg(II).…”

Graphitic and amorphous C-dots share common characteristics in their photoluminescence behavior. However, the graphitic dots have a lead as electrocatalyst for fuel cells, sensitizers, and electron acceptors for solar cells.The emergence of carbogenic nanoparticles (C-dots) as a new class of photoluminescent (PL) nanoemitters is directly related to their economical preparation, nontoxic nature, versatility, and tunability. C-dots are typically prepared by pyrolytic or oxidative treatment of suitable precursors.While the surface functionalities critically affect the dispersibility and the emission intensity of C-dots in a given environment, it is the nature of the carbogenic core that actually imparts certain intrinsic properties. Depending on the synthetic approach and the starting materials, the structure of the carbogenic core can vary from highly graphitic all the way to completely amorphous. This critical review focuses on correlating the functions of C-dots with the graphitic or amorphous nature of their carbogenic cores. The systematic classifi cation on that basis can provide insights on the origins of their intriguing photophysical behavior and can contribute in realizing their full potential in challenging applications.Keywords : luminescence ; nanostructure ; carbonization REVIEW DISCUSSION POINT ▪ C-dots set an example that low-cost, non-toxic materials can effectively supplant highly engineered, yet toxic compounds in challenging applications.
