A Study of the Emission from ZnO:S and ZnS:Mn.Te to Create an Efficient White Light Emitting Core/Shell Nanoparticle
Abstract:

In this study, the visible emission mechanism of ZnO:S (~520 nm) and ZnS:Mn,Te (~650 nm) is to be investigated. Understanding the emission from these two high intensity phosphors will lead to a better understanding of the anion doping that is taking place. Also a novel idea for a single core/shell nanoparticle that emits white light is presented. This includes preliminary data from a ZnS/ZnO core/shell particle. We wish to use the properties of ZnO:S and ZnS:Mn,Te in this particle so a better understanding of these two materials is needed. Emission spectra are shown for all materials and suggestions for future work to meet this goal.
