Abstract
The influence on the emission property of CdSe quantum dots arising from propagating surface plasmon polaritons based on interconnected periodic gold nanoarrays with a large area of 1 cm2 is reported. Variation in the structural parameters allows us to tune the surface plasmon resonance to the emission band of quantum dots, which can result in an enhancement up to 54 times in the external quantum efficiency. Our strategy for the enhancement of luminescence efficiency from semiconductor quantum dots should be useful for the creation of high efficiency solid state emitters.
