TL;DR: Carbon dots represent an emerging class of fluorescent materials and provide a broad application potential in various fields of biomedicine and optoelectronics as discussed by the authors, and the applicability of carbon dots as components of light emitting diodes, which include carbon dot based electroluminescence, optical downconversion, and hybrid plasmonic devices.

TL;DR: It is reported that a switchable EL behavior with white emission has not been observed thus far in single emitting layer structured nanomaterial LEDs, and this interesting current density-dependent emission is useful for the development of colorful LEDs.

TL;DR: This work shows how ultrasmall carbon dots (CDs) fluorescing strongly across the visible spectrum can be surface functionalized and incorporated into highly flexible hybrid materials by combination with ionic liquids within silica gel networks to form CD-ionogels with properties promising for fabrication of flexible displays and other optical technologies without the use of any toxic materials.

TL;DR: In this paper, a facile one-step reverse precipitation method was proposed to synthesize water-dispersible, biocompatible, and carboxylate-functionalized superparamagnetic magnetite (Fe3O4) nanoparticles with the help of a sodium citrate salt.

TL;DR: A new computational approach was proposed to calculate the total number of Pb and Se atoms in different sized particles, which played a key role on the accurate determination of the strongly size-dependent extinction coefficient.
