The interposition of a thin‐metal buffer between the anode and active layers of an organic light emitting diode (OLED) can significantly improve hole injection. Experimental results of devices using silver, gold, and gold‐palladium layers are presented and correlated to their respective work functions. A significant reduction in resistivity was observed with a silver buffer layer in a bilayer OLED device. © 2006 Wiley Periodicals, Inc.
