Lead-free CuInSe2 (CISe) quantum dots (QDs) with tunable emission (789-1390 nm) were synthesized via hot injection. CISe photodetectors achieved responsivity of 5.3 A/W and detectivity of 5.6×1012 Jones at 950 nm. Integration with ZnCdSeS QDs further enabled efficient infrared-to-visible up-conversion.
