Abstract

Abstract:

A new method is presented of enhancing the organic electroluminescent(EL) efficiency by using poly (methylmethacrylaie) (PMMA) as barrier layers which play the role of controlling the electron-hole recombination in the organic EL materials. The organic EL device with one layer of 8-hydroxyquinoline derivalive-metal complexes-(Alq3, Znq2) as the EL-emitting layers, and two layers of EL emitting materials deposited on PMMA Langmuir-Blodgett films (PMMA/Alq3, PMMA/Znq2) sandwiched between indium/tin oxide (ITO) and aluminum electrodes have been fabricated, respectively. The evidence reveals that the LB film takes an importance to raising the 8-hydroxyquinoline derivative-metal complexes EL efficiency.
