Abstract

A model is proposed to study the hybrid exciton in a quantum dot--dendrimer systems. The semiconductor organic hybrid exciton is studied using a ``real space'' Green's function method and a diagrammatic technique. The energy of the hybrid exciton as well as the Green function matrix elements have been calculated for different quantum dot(QD-)dendrimer systems, and the method can be applied for systems with different structures. Using the double-time Green's functions the optical processes can be calculated. The optical properties of the systems are controllable by the size and structure of the QD-dendrimer systems.
