Paper Abstract

In this paper, we study the computational modeling of the localized surface plasmonic and scattering field effect arising from of gold nanorods. We also report the synthesis and optical characterization of core-spacer-shell nanocomposites composed of gold nanorods coated with SiO2 and finally coated with Y2O3:Er3+/Yb3+ (Aunanorods@mSiO2@Y2O3:Er3+/Yb) through a layer-by-layer method. Preliminary upconversion analysis of singly (Aunanorods@mSiO2@Y2O3:Er3+/Yb) at 980 excitation indicates that the composition has to be optimized to understand the role of silica as a spacer and near field enhancer (gold nanorod) in the system.
