From: Heavily doped n-type PbSe and PbS nanocrystals using ground-state charge transfer from cobaltocene
Cobaltocene doping of PbSe and PbS NC solutions.
(a) The redox potential of cobaltocene (dashed gray line) in comparison to the conduction band states in PbSe (solid black line) and PbS (dashed-dotted black line) NCs. Symbols correspond to samples from the present study. (b) The effect of electron injection from cobaltocene on optical absorption of a NC. NC-size dependent absorption spectra of PbSe (c) and PbS (d) NCs before (solid lines) and after (dashed lines) treatment with cobaltocene; color coding matches that in panel a.
