A theory for excitons in complex quantum nanostructures with complicated geometries and strong coupling between nanostructures is presented. Effective mass models with screened Coulomb interaction give reasonable ground-state energies for excitons in T-shaped quantum wires, coupled T-quantum wires and quantum dot quantum wells, provided the effects of complex geometry are included. A sizable shift between exciton states in quantum wells and T-shaped wires occurs due to a 40% enhancement in binding energy, confinement in the wire, and significant interwire coupling.
