摘要：

The photoluminescence (PL) enhancement of a Ag nanoparticle and near-infrared quantum dots (QD) plasmon/fluorophore system was investigated. Different enhancement mechanisms were obtained by tuning surface plasmon resonance of the Ag film and PL of the QDs. A maximum enhancement factor of 2.8 was achieved.
