Lighting up the Electrochemiluminescence of Carbon Dots through Pre- and Post-Synthetic Design.

Carbon dots (CDs), defined by their size of less than 10 nm, are a class of photoluminescent (PL) and electrochemiluminescent (ECL) nanomaterials that include a variety of carbon-based nanoparticles. However, the control of their properties, especially ECL, remains elusive and afflicted by a series of problems. Here, the authors report CDs that display ECL in water via coreactant ECL, which is the dominant mechanism in biosensing applications.

Oxide Addition to a Reactive Polysulfide Flux: Synthesis of K Ba[Ti OS ] Containing Isolated [Ti OS (S ) ] Clusters.

The zero-dimensional cluster compound K Ba[Ti OS (S ) ] has been synthesized from a reactive flux similar to that of K S and Ti used in the synthesis of the one-dimensional compound K Ti S , but augmented by the deliberate introduction of TiO . The picture shows the structure of the [Ti OS (S ) ] ion.
