Electrochemistry in Carbon‐based Quantum Dots
Chemistry – An Asian Journal, 2020AbstractElectrochemistry belongs to an important branch of chemistry that deals with the chemical changes produced by electricity and the production of electricity by chemical changes. Therefore, it can not only act a powerful tool for materials synthesis, but also offer an effective platform for sensing and catalysis. As extraordinary zero‐dimensional

Carbon “quantum” dots for optical bioimaging
Journal of Materials Chemistry B, 2013Carbon dots, generally referring to small carbon nanoparticles with various levels of surface passivation, have emerged as a new class of quantum dot-like fluorescent nanomaterials. Since the original report in 2006, carbon dots have been investigated by many research groups worldwide, with major advances already made in their syntheses, structural and

Observing Carbon Dots in Putative Boron Nitride Quantum Dots
Nano LettersBoron nitride quantum dots (BNQDs) have garnered a significant amount of attention in recent years due to their attractive optical properties, high stability, low toxicity, and good biocompatibility. However, our study reveals a critical mischaracterization in this field, demonstrating that some so-called BNQDs are, in fact, carbon dots (CDs) formed ...

Luminescence of carbon quantum dots in amorphous carbon
Journal of Optical TechnologySubject of study. The luminescence spectrum of amorphous protonated carbon (a-C:H) containing carbon quantum dots is studied. Aim of study. How the peak in the luminescence spectrum of a-C:H is affected by the presence of fragments with different configurations is determined. Method. The typical spectra are compared against those of the closest analogs:
