Fig. 3: Effect of ligand passivation on nanoplatelet band gap.
From: Controlling light emission from semiconductor nanoplatelets using surface chemistry
Optical transition energies of CdSe nanoplatelets passivated by different ligands: a DFT gaps between the valence and conduction states in CdSe nanoplatelets, comparing nanoplatelets that are passivated with different ligands (\({E}_{{{{\rm{g}}}}}^{\ell }(d)\)). b Comparison of theory with experiment. Theoretical gaps for the passivated nanoplatelets are shown as dots superimposed on the experimental absorbance data8. We observe excellent agreement between the calculated gaps and the experimental absorption onset. c Band gap shift parameter \(\alpha=\Delta {E}_{{{{\rm{g}}}}}^{\ell }(d)\) for the different ligands as a function of nanoplatelet thickness. Source data are provided as a Source Data file.
