Fluorescent carbon dots: rational synthesis, tunable optical properties and analytical applications

Carbon quantum dots: synthesis, properties and applications

Carbon quantum dots (CQDs, C-dots or CDs), which are generally small carbon nanoparticles (less than 10 nm in size) with various unique properties, have found wide use in more and more fields during the last few years. In this feature article, we describe the recent progress in the field of CQDs, focusing on their synthetic methods, size control, modification strategies, photoelectric propertie...

Fluorescent carbon dots from mono- and polysaccharides: synthesis, properties and applications

Fluorescent carbon dots (FCDs) are an emerging class of nanomaterials made from carbon sources that have been hailed as potential non-toxic replacements to traditional semiconductor quantum dots (QDs). Particularly in the areas of live imaging and drug delivery, due to their water solubility, low toxicity and photo- and chemical stability. Carbohydrates are readily available chiral biomolecules...

Germanium quantum dots: Optical properties and synthesis

Three different size distributions of Ge quantum dots (>200, 110, and 60 A) have been synthesized via the ultrasonic mediated reduction of mixtures of chlorogermanes and organochlorogermanes (or organochlorosilanes) by a colloidal sodium/potassium alloy in heptane, followed by annealing in a sealed pressure vessel at 270 “C. The quantum dots are characterized by transmission electron microscopy...
