Li et al. report ZnF2 as the additive to balance shell growth rate of ZnSe in large InAs/InP/ZnSe/ZnS core-multishell quantum dots. An in-situ photo-crosslinking blended hole-transport layer is used to modulate the energy levels for balanced carrier dynamics in NIR LEDs, enabling peak efficiency of 20.5% and operational half-lifetime of 550 h at 50 W sr−1 m−2.
