Ultrasmall Color‐Tunable Copper‐Doped Ternary Semiconductor Nanocrystal Emitters

Abstract

Surface cation exchange of ZnII for InIII allows the emission of Cu-doped zinc indium selenide semiconductor nanocrystals to be tuned in the range of 660–540 nm, and thus the emission color to be varied from red to green (see picture; the arrow indicates increasing ZnII content).
