Blended films in a matrix of Zeonexs, produced at different concentrations, showed different contributions of dimer and monomer emissions in a prompt time frame, e.g. less than 50 ns. In contrast, the phosphorescence (e.g. emission from the triplet state) shows no significant effect on dimer formation, although strong dependence of the phosphorescence intensity on concentration is observed, leading to phosphorescence being quenched at higher concentration.en-USrestritoArtigo publicado em periodicohttps://pubs.rsc.org/en/content/articlehtml/2019/cp/c8cp07005ahttps://doi.org/10.1039/C8CP07005A
