Abstract
Steady-state photocurrent in poly(N-vinylcarbazole)(PVCz) (26,48 wt%)/poly( methyl methacrylate)(PMMA) blends is for the first time measured. The PVCz( 26,48 wt%)/PMMA blends showed almost the same carrier-generation efficienci es at electric fields higher than 1 x 10(5) V.cm(-1). The results are expla ined by high miscibility of the PVCz(26,48 wt%)/ PMMA blends, suggesting th e existence of PVCz chains in continous PMMA-rich phase in the phase-separa ted structure. The miscibility is also evaluated by means of excimer fluore scence of PVCz in these blends and fluorescence microscopy.
