Efficiently alternating current driven tandem organic light-emitting devices with (Ag/4,7-diphenyl-1,10-phenanthroline)n interconnecting layers
Alternating current (AC) driven tandem organic light-emitting devices (OLEDs) in which an invert unit is connected to a normal unit with [Ag/4,7-diphenyl-1,10-phenanthroline (Bphen)]n interconnecting layers (ILs) are demonstrated. The current-voltage and capacitance-voltage characteristics of differ...

Zusammenfassung: | Alternating current (AC) driven tandem organic light-emitting devices (OLEDs) in which an
invert unit is connected to a normal unit with [Ag/4,7-diphenyl-1,10-phenanthroline
(Bphen)]n interconnecting layers (ILs) are demonstrated. The current-voltage
and capacitance-voltage characteristics of different devices with or without ILs
demonstrated that (Ag/Bphen)n ILs possess excellent charge generation and
electron injection abilities. Thus, (Ag/Bphen)n ILs could offer sufficient
electrons for two units to realize radiation-recombination under AC bias. Efficient
AC-driven OLEDs in which the color and brightness can be tuned independently by changing
the AC bias are achieved. |
