Effect of X-type ligands on the stability of electron charged CdSe QDs. (A) Energies of CB edge, in-gap level, and VB edge of Cd₆₈Se₅₅X₂₆ QDs in the reduced configuration at ⟨n⟩ = 2, with X = Cl, Br, I, etc., as indicated on the x-axis. (B) Correlation between ΔE_R and ΔE_trap with reduction of Cd₁ (black circles) or Cd₂ (red triangles). The gray dashed line is a linear fit to the data points.
