Abstract

Abstract : In article1702098, by Bart van Dam, Minjie Li, and co‐workers, single‐dot spectroscopy is used to show that individual carbon dots already exhibit excitation‐dependent photoluminescence, very similar to the ensemble of carbon dots. Characteristic excitation‐dependent emission spectra are identified, indicating the presence of multiple active emission sites within a carbon dot. This shows that it is possible to engineer different types of electron transitions in nanoscopic dimensions through facile chemical synthesis.
