Semiconductor nanocrystals have drawn significant interest due to their light absorption and electron transport properties which are mostly used for solar cells materials. Electron transfer and light absorption in very small CdSe quantum rods (QRs) (diameter of 1.8 nm) coupled with electron acceptors Methyl Viologen (MV+2) were investigated by Transient Absorption spectroscopy.
