Abstract:Recent experiments have shown that hole traps could be suppressed in polymer light‐emitting diodes under current stress by diluting the light‐emitting conjugated polymers within an “inert” large‐bandgap host material. However, it is unclear why there is an enhanced dilution effect in partially miscible blends rather than fully miscible blends, as intuition would suggest that better miscibility leads to better dilution. In this work, we propose a cascade analysis by combining multiple fluorescence microscopic t… Show more
