Blue Emissive Carbon Quantum Dots (CQDs) from Bio-waste Peels and Its Antioxidant Activity
In this work, Carbon Quantum Dots (CQDs) are synthesized from agro-waste Ananas comosus by facile hydrothermal treatment. The synthesized CQDs are characterized using powder X-ray diffraction analysis, Fourier-transform infrared, UV–Visible spectral analysis and quantum yield (QY) measurements. The...

Zusammenfassung: | In this work, Carbon Quantum Dots (CQDs) are synthesized from agro-waste
Ananas comosus
by facile hydrothermal treatment. The synthesized CQDs are characterized using powder X-ray diffraction analysis, Fourier-transform infrared, UV–Visible spectral analysis and quantum yield (QY) measurements. The formation of CQDs with a mean particle size of 2.4 nm is measured using HR-TEM analysis. The fluorescence properties of CQDs show strong blue emission radiation with a QY of 10.65%. Antioxidant assay of the CQDs were assessed against DPPH (2, 2-diphenyl-1-picrylhydrazyl), Super oxide anion radical scavenging, hydroxyl radical scavenging and hydrogen peroxide radical scavenging activities. The results suggest that agro-waste is also one of the promising materials for optical switching devices and also it have good medicinal value by extracting drugs. |
