dc.description.abstract | The short device lifetime of blue polymer light-emitting diodes (PLEDs) is still a bottleneck for commercialization of self-emissive full-color displays. Since the cathode in the device has a dominant influence on the device lifetime, a systematic design of the cathode structure is necessary. The operational lifetime of blue PLEDs can be greatly improved by introducing a three-layer (BaF(2)/Ca/Al) cathode compared with conventional two-layer cathodes (BaF(2)/Al and Ba/Al). Therefore, the roles of the BaF(2) and Ca layers in terms of electron injection, luminous efficiency, and device lifetime are here investigated. For efficient electron injection, the BaF(2) layer should be deposited to the thickness of at least one monolayer (similar to 3 nm). However, it is found that the device lifetime does not show a strong relation with the electron injection or luminous efficiency. In order to prolong the device lifetime, sufficient reaction between BaF(2) and the overlying Ca layer should take place during the deposition where the thickness of each layer is around that of a monolayer. | - |
