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.

等离子体增强:耦合到等离子体金纳米杯阵列的溶液中CuInS2量子点的光致发光增强(Small 33/2017)

Rana Biswas,Han Htoon及其同事在编号1700660中证明了溶液中无毒的CuInS 2 / ZnS量子点与等离子体金纳米杯阵列之间的强激子-等离子体激元耦合。由于集中在等离子体纳米杯腔底部的强电磁场,量子点的光致发光衰减率可以提高一个数量级以上。该系统为生物传感等应用开辟了新的可能性。
