Two publications have highlighted Ames Laboratory scientists using Raman and photoluminescence spectroscopies to quantify lattice strain and photoluminescence behavior in germanium-tin nanoparticles. The team is studying their use as a photovoltaic material.
Scientists mentioned in the articles include Emily Smith and Javier Vela, both researchers in the Chemical and Biological Sciences division of the Ames Laboratory. Smith is a professor of chemistry, and Vela is an associate professor of chemistry, at Iowa State University.
The scientists original paper, “Germanium–Tin/Cadmium Sulfide Core/Shell Nanocrystals with Enhanced Near-Infrared Photoluminescence,” was published in Chemistry of Materials, June 27, 2017.
