15 March 2016 Plasmonically enhanced photoluminescence of nanoscale semiconductors
Author Affiliations +
Recent work has shown that plasmonic structures enhance the emitted light of nanoscale semiconductor materials, such as the photoluminescence of colloidal quantum dots (QDs) and MoS2 2D materials. This project will compare the photoluminescence of CdSe colloidal quantum dots and MoS2. A variety of studies will be performed such as photobleaching effects, how photoluminescence relates to lifetime of sample, and polarization studies. In addition, this project will further the understanding of plasmonically enhanced photoluminescence between these semiconductor nanostructures and metal nanostructures. Initial studies will drop cast colloidal metal nanospheres onto quantum dots and MoS2, while future work will fabricate gold structures with electron beam lithography.
