Abstract

An increase in the efficiency for a terbium-based OLED was achieved by introducing gold nanoparticles into the PEDOT:PSS hole injection layer and was mainly due to the improvement in carrier injection and the reduction of the excited-state lifetime. The introduction of plasmon-resonant gold nanoparticles resulted in a 50% increase in the Tb(czb)₃TDZP luminance, which reached 480 cd m^-2 and is the highest result for OLEDs based on aromatic carboxylates.
