Abstract

Read online

CdSe/CdS tetrapods exhibit the unusual trait of two-colour multiexcitonic emission. Here Mishraet al. study this type of dual emission at the single-nanocrystal level. By tuning arm diameter and length they seek to understand shape-dependent evolution of the emission and of blinking behaviour.
