Highly luminescent carbon nanodots by microwave-assisted pyrolysis.
نویسندگان
چکیده
Carbon nanodots (CDs) with a low cytotoxicity have been synthesized by one-step microwave-assisted pyrolysis of citric acid in the presence of various amine molecules. The primary amine molecules have been confirmed to serve dual roles as N-doping precursors and surface passivation agents, both of which considerably enhanced the fluorescence of the CDs.

Photoluminescent carbon nanodots (CDs) have attracted growing interest very recently. In comparison to fluorescent semiconductor quantum dots (QDs), which are usually composed of heavy metals as the essential elements to achieve high performance fluorescence, the carbon nanodots are advantageous both in their green synthesis and good biocompatibility for biomedical applications. So far, various...
متن کاملAmino acids as the source for producing carbon nanodots: microwave assisted one-step synthesis, intrinsic photoluminescence property and intense chemiluminescence enhancement.
In this communication, we report a general strategy for the production of carbon nanodots (CDs) by microwave irradiation of amino acids in the presence of acid or alkali. The resultant CDs exhibit strong photoluminescence and intense chemiluminescence enhancement of the NaIO(4)-H(2)O(2) system.

متن کاملSynthesis of biocompatible multicolor luminescent carbon dots for bioimaging applications.
Water-soluble carbon dots (C-dots) were prepared through microwave-assisted pyrolysis of an aqueous solution of dextrin in the presence of sulfuric acid. The C-dots produced showed multicolor luminescence in the entire visible range, without adding any surface-passivating agent. X-ray diffraction and Fourier transform infrared spectroscopy studies revealed the graphitic nature of the carbon and...
متن کاملErratum: Analytical Sciences, 2015, Vol. 31, No. 6, p. 481. Photoluminescent Detection of Nitrite with Carbon Nanodots Prepared by Microwave-assisted Synthesis.
A photoluminescent detection method for nitrite with high selectivity and sensitivity using carbon nanodots (CNDs) is demonstrated. The selectivity of nitrite is accomplished by a highly specific diazotization reaction between nitrite and p-phenylenediamine (p-PDA). In the presence of nitrite, p-PDA easily reacts to form the diazonium cation in the acidic aqueous solution. By alkalization of th...
