"quantum dots promising as photocatalysts for promoting photoredox chemistry, generating hot electrons enhancing photoreduction efficiencies, but achieving hot-electron generation under mild conditions is challenging... overcome with 2-photon spin-exchange Auger in Mn²⁺-doped CdS/ZnS utilizing visible-light-absorption... uses just 1% of light energy normally required... enables on/off generation of hot electrons by modulating light output intensity, facilitating programmable assembly-point cross-coupling cascades "
