Schematic diagram illustrating the effect of the light on the spin selectivity. (A) Before photoexcitation, the CdSe-NPs are positively charged and electrons are transferred with their spin aligned parallel to their velocity. (B) When the NPs are photoexcited, the NPs become negatively charged. The electric field on the AL8-CdSe is in the opposite direction and thus the electrons with spin antiparallel to their velocity are preferentially transferred.
