Influence of spin relaxation on excitonic nonlinearity in organic-inorganic hybrid quantum-well materials

This study investigates the exciton spin relaxation between optically allowed excitons in an organic-inorganic hybrid quantum-well material (C/sub 6/H/sub 13/ H/sub 3/)/sub 2/ PbI/sub 4/. Results show that the fast spin relaxation ( 3 fs) strongly influences the excitonic nonlinearity.
