One-step synthesis of alloyed dual-emitting semiconductor nanocrystals.

Alloyed Zn(1-x-y)Cd(x)Mn(y)Se nanocrystals exhibiting bright intrinsic dual emission attractive for ratiometric optical nanothermometry are reported. Relative to earlier materials with related dual emission, these alloy nanocrystals require shorter syntheses, contain less Cd(2+), and show dual emission that is less sensitive to nanocrystal shape, size, or surfaces.
