Abstract
In this paper, a highly conductive and strongly absorptive organic thin film by doping Ag into N, N′ -bis (2,6-di-isopropylphenyl)-1,7-bis (4-methoxy-phenyl) perylene-3,4,9,10-tetracarboxydiimide (MPPDI) was demonstrated. Strong absorption resulted from the broadband absorption of MPPDI at visible range and plasmon-enhanced absorption around 420 nm of Ag nanoparticles. Ag dopants in MPPDI acted as quenchers, which resulted in a dramatic decrease in photoluminescence intensity of MPPDI. Besides, J-V characteristics of Ag:MPPDI thin film changed from trapped-charge-limited current to Ohmic conduction with increasing Ag concentrations. Conductivity of 1.15× 10-6 cm was achieved when MPPDI/Ag=5:1. This organic thin film has potential applications for low-reflectance organic light-emitting diode and organic photovoltaic device. © 2009 American Institute of Physics.
