| 英文摘要 | Paramagnetic ions-doped quantum dots (QDs) are attractive dual-modal imaging agents for fluorescence and magnetic resonance imaging. In this work, we report the synthesis of water-soluble Gd-doped CulnS(2) (CulnS(2):Gd) QDs by incorporating paramagnetic Gd3+ ions into CulnS(2) QDs in organic solvents and subsequent surfactant-assisted phase transfer. The Gd doping was realized through a simple heat-up reaction and the growth kinetics of Gd-doped CulnS(2) QDs was discussed on the basis of the temporal evolution of the sizes and elemental compositions of the QDs. The effect of Gd doping on the photoluminescence properties of the QDs was also investigated. After encapsulation with polymer surfactants, the obtained water soluble CulnS(2):Gd QDs exhibited excellent aqueous stability, ultra small size and a large longitudinal relaxivity (r(1)) of 12.84 mM(-1) s(-1), showing great promise as dual fluorescent-paramagnetic nanoprobes for bio-imaging applications.
