Enhancing optical nonlinearity through engineered exciton coupling in organic-inorganic nanocomposites
We show enhancement in optical nonlinear absorption by engineering the coupling between excitons of 3,4,7,8-naphthalenetetracarboxylic dianhydride (NTCDA) and ZnO nanowires. Energy transfer between the excitonic systems and exciton scattering are found to be competing processes.
