TL;DR: Near-infrared-emissive polymer-carbon nanodots possess two-photon fluorescence; in vivo bioimaging and red-light-emitting diodes based on these PCNDs are demonstrated.

TL;DR: In this paper, the authors reviewed recent progress on CDs utilized for photocatalysis from different perspectives, including the following three parts: classification and synthesis, mechanism of CDs-derived photocatalysts as well as the applications for environmental issues (up-converted photoluminescence (PL) and energy conversion).

TL;DR: Electrochemical tests reveal that the as-formed Ru@CQDs exhibits excellent catalytic behavior with an onset overpotential of 0 mV, a Tafel slope of 47 mV decade-1, and good durability, which is superior to the current commercial Pt/C and most noble metals, non-noble metals, and nonmetallic catalysts under basic conditions.

TL;DR: A facile method is reported to prepare an efficient and robust Ru-M (M=Ni, Mn, Cu) bimetal nanoparticle and carbon quantum dot hybrid (RuM/CQDs) for pH-universal HER, which exhibits outstanding HER performance at all pH levels.

TL;DR: It is demonstrated that polythiophene, deposited on the top of CsPbI2 Br, can significantly reduce electron-hole recombination within the perovskite, which is due to the electronic passivation of surface defect states, and the interfacial properties are improved by a simple annealing process.
