In article number 1700660, Rana Biswas, Han Htoon, and co-workers, demonstrate a strong exciton-plasmon coupling between non-toxic CuInS2/ZnS quantum dots in solution and a plasmonic gold nanocup array. The photoluminescence decay rate of quantum dots can be enhanced by more than an order of magnitude due to the intense electromagnetic field concentrated at the bottom of the plasmonic nanocup cavity. This system opens up new possibilities for applications such as in biosensing.
