Résumé : This present work reports the effect of nanoparticle concentration on the electroluminescence decay from exciton dissociation in organic-inorganic layers. The theoretical method for electroluminescence decay is based on the exciton dynamics of both the Frenkel exciton and Wannier exciton density. The results show that the electroluminescence intensity has been significantly influenced by the Förster transfer mechanism. In particular, we have found good agreement with experimental results observed in organic MEH-PPV and inorganic CdSe nanoparticles. These findings suggest that this hybrid material could be a promising candidate for optoelectronic devices.
