Research topics from publications: Carrier Density, Effective Mass, and Nuclear Relaxation Pathways in Plasmonic Sn:In2O3 Nanocrystals. Representative work: Correlating changes in carrier density arising from incorporating dopant ions into the lattice of a plasmonic semiconductor nanocrystals (NCs) with the observed physical properties at the elemental level can improve our understanding of these materials. Here, we investigate Sn:In2O3 (ITO) NCs, a well-known near-infrared plasmonic system, by analyzing the induced carrier density changes that occur in the optical response and the 119Sn nuclear relaxation rates. The carrier density, as evaluated by a chemical titration method, is correlated to the Burstein–Moss shift and the plasmon frequency to evaluate the effectiveness of the Drude-Lorentz model. Comparison of the values for carrier density
