Using shape to turn off blinking for two-colour multiexciton emission in CdSe/CdS tetrapods

CdSe/CdS tetrapods exhibit the unusual trait of two-colour multiexcitonic emission. Here Mishra et 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.
