Abstract

We design, synthesize, and characterize multi-shell quantum dot structure of an indium phosphide core surrounded by zinc chalcogenide shells. A simple mathematical model describing the wave function of electronhole pairs enabled us to design ZnSe and ZnS shells to confine the carriers inside the core region effectively. The result indicates that the designed multi-shell quantum dots show improved optical properties that are more robust against chemical and photo-environmental changes.
