Hot electron transfer in Zn–Ag–In–Te nanocrystal–methyl viologen complexes enhanced with higher-energy photon excitation

The dynamics of hot electron transfer from Zn–Ag–In–Te (ZAITe) nanocrystals (NCs) to adsorbed methyl viologen (MV(2+)) were investigated by transient absorption spectroscopy. The bleaching of the exciton peak in the ZAITe NC–MV(2+) complexes evolved faster than that of ZAITe NCs. The hot electron tr...

Sumario:The dynamics of hot electron transfer from Zn–Ag–In–Te (ZAITe) nanocrystals (NCs) to adsorbed methyl viologen (MV(2+)) were investigated by transient absorption spectroscopy. The bleaching of the exciton peak in the ZAITe NC–MV(2+) complexes evolved faster than that of ZAITe NCs. The hot electron transfer efficiency increased from 45% to 72% with increasing excitation photon energy.
