Polymer Light-Emitting Diodes with Cathodes Printed from Conducting Ag Paste

All‐printable polymer light‐emitting diodes (PLEDs) are realized by the development of a new bilayer cathode that combines Ag paste with aminoalkyl‐ substituted polyfluorenes. PLEDs with a printed Ag‐paste cathode (see figure) show comparable device performance to those devices incorporating a low‐w...

Zusammenfassung:All‐printable polymer light‐emitting diodes (PLEDs) are realized by the development of a new bilayer cathode that combines Ag paste with aminoalkyl‐ substituted polyfluorenes. PLEDs with a printed Ag‐paste cathode (see figure) show comparable device performance to those devices incorporating a low‐work‐function cathode (Ba/Al) that is deposited thermally.
