Doped Nanocrystals: Tuning the Emission Colors of Semiconductor Nanocrystals Beyond their Bandgap Tunability: All in the Dope (Small 22/2013)

Transition metal ion doped semiconductor nanocrystals emitting in the entire visible light spectrum are reported by N. Pradhan and co-workers on page 3753. The doping of Ag, Cr, Ni, and Cu ions is performed with a fixed size/composition of the CdxZn1−xS alloy host semiconductor nanocrystals and blue, green, yellow, and red (BGYR) emission colors are obtained, respectively. By designing different dual-doped nanocrystals, the dopant state positions are correlated.
