| Abstract(in English) | In order to improve the running durability of organic light emitting devices(OLEDs), various single layer devices were examined for gradual increases in driving voltage during continuous d.c.operation under a constant current. The rate of voltage increase for aluminum tris(quinoline-8-olate)(Alg), which is the most popular material for electron transport layer(ETL), was largest, however, those for many hole transporting materials were small. The rates of voltage increase depended on the electric field strength across the organic layer. Therefore dominant contribution to voltage increases were attributed to changes in the ETL, which may depend on electric field strength and amount of injected holes into ETL. |
