Water-soluble Ag-doped InP/ZnS quantum dots (QDs) with high photoluminescence quantum yield were synthesized and characterized. Their maximum two- and three-photon absorption cross sections are determined as ∼1.7 × 10 4 GM at 820 nm and ∼1.7 × 10 -76 cm 6 s 2 photon -2 at 1260 nm. Importantly, for the first time, we demonstrated that Ag-doped InP/ZnS QDs can be used for type-I photodynamic therapy and are more suitable for the hypoxic environment of tumors.
