(a) TRPL of SPFLMW at 424 nm for optical excitation at 387 nm, that of Ir(btp)2acac doped SPFLMW is provided in the (b). The open circles are single exponential fits and average fall times (over three samples) of 293 ps and 36 ps can be obtained for pure and Ir(btp)2acac doped SPFLMW, respectively. These TRPL measurements were carried out in device geometry with the structure: ITO/PEDOT:PSS/emitting layer/TPBI/Ca/Al.
