We report the fabrication and characterization of inverted bottom-emission polymer light-emitting devices doped with an organic salt. Unlike conventional organic light-emitting devices, the bottom indium tin oxide (ITO) and top aluminum layers act as the cathode and anode for the inverted devices, respectively. Even though the device structure is reversed in the inverted devices, it was found that their performance is comparable to that of conventional devices. The performance enhancement was attributed to the utilization of a zinc oxide (ZnO) layer and the doping of the organic salt.
