英文摘要 | Organic electroluminescent (EL) devices with a bilayer structure (ITO/LB film/PBD/Al) were fabricated with an Langmuir-Blodgett (LB) film of amphiphilic complex bis[N-hexadecyl-8-hydroxy-2-quinolene carboxamide] lanthanum[La(HQ)(2)Cl] as the emitting material. Excellent performance of the EL devices originates from the insertion of an electron transport layer between the electrode and the emitting layer. Greenish-yellow EL emission with a luminance of about 1 219 cd/m(2) was observed with a low voltage drive(7.5 V). The number of the layers of LB films and the deposited surface pressure have a strong influence on the I-V characteristics, EL intensity, as well as break-down voltage of the EL devices. When the LB films were prepared at the surface pressure of 25 mN/m, the current density crossing this kind of diodes had stronger nonlinear I-V characteristics and the organic EL device had a higher EL intensity than another device prepared at lower surface pressure (5 and 15 mN/m). At a lower surface pressure, there may be some point defects or pinholes in the LB film, in which the high tunnel current would increase exponentially with the field, leading to an increase in the current density crossing the EL device and a decrease in the recombination probability of electrons and holes at a higher voltage. |
