Nonlinear Optical Response of Hybrid Exciton State in Quantum Dot- Dendrite Systems

Abstract

Abstract A “real space” Green’s function method and a diagrammatic technique are used to study the optical response of the semiconductor-organic hybrid exciton in quantum dot-dendrimer system. The energy of the hybrid exciton and the linear and non-linear susceptibilities have been calculated for a sample of quantum dot-dendron ligand. Enhanced non-linearity is obtained, which is controlable by the number of generations, the size and structure of the QD-dendrimer systems.
