Ag2s Quantum Dots

Near-infrared emitting semiconductor quantum dots (NIRQDs) are popular fluorescent probes due to better penetration depth and elimination of tissue autofluorescence.

Plasmon–exciton interaction strongly increases the efficiency of a quantum dot–based near-infrared photodetector operating in the two-photon absorption mode under normal conditions.
