AlCl₃-promoted growth of alkylated carbon dots with an enhanced nonlinear optical response

Abstract

Carbon dots (CDs) have attracted increasing attention due to their wide potential applications. However, the rational design of task-specific CDs is still in its infancy. Specifically, some CDs have shown...

Aluminum-Doped Carbon Dots for the Simultaneous Selective Detection of Five Tetracycline Antibiotics

“…The interaction between Al and TC had been further veri ed by Li and coworkers [20], who reported amino-functionalized Al-MOF for uorescent detection of tetracycline in milk. The Al-doped CDs were rarely reported and were never considered for tetracycline antibiotics determination [21][22][23].…”

Rapid preparation of N,B-codoped carbon quantum dot based films with strong two-photon absorption and optical limiting effect

“…Moreover, large π-electron delocalization can be realized by doping with an element with strong electron-accepting ability and modifying by functional groups with strong electron-accepting ability on the surface of CQDs, such as nitro, amino, and carboxyl groups, which will promote the internal electron transfer of CQDs and thus enhance the two-photon absorption ability of CQDs. 17,18 Solid materials with good two-photon absorption properties can be obtained by dispersing two-photon absorption CQDs into solid substrates, such as nanoporous SiO 2 and silicate gel-glasses. 19,20…”

Water Soluble PMPC-Derived Bright Fluorescent Nitrogen/Phosphorous-Doped Carbon Dots for Fluorescent Ink (Anti-Counterfeiting) and Cellular Multicolor Imaging

“…Recently much effort has been made in the preparation of CDs from biowaste [ 30 , 31 ] and plant sources [ 32 , 33 ]. Apart from the small molecules, polymers are employed as carbon sources for the synthesis of CDs [ 34 , 35 , 36 , 37 , 38 , 39 ]. Any functional group that is present in small molecules or polymers will be retained as surface functional groups in CDs [ 40 , 41 , 42 ].…”
