Abstract In the present paper, polymer-based light-emitting diode employing N-vinylcarbazole (PVK) doped with dilute phosphorescent dye factris-(2-phenylpyridine) iridium [Ir(ppy)3] and fluorescent dye 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) as active layer was fabricated in order to compare the formation cross-sections of triplet exciton and singlet exciton. According to the changes in the electroluminescence (EL) spectrum and the relative intensity of photoluminescence (PL) spectrum, we deduce that the exciton formation cross-section of Ir(ppy)3 is larger than that of DCJTB.
