|Title:||ELECTRODE AND ORGANIC ELECTROLUMINESCENT COMPONENT APPLYING SAME|
Related to the field of organic electroluminescence, specifically related to an electrode and an organic electroluminescent component applying same. The electrode comprises a first membrane (1) and a second membrane (2) in a stacked arrangement. The first membrane (1) is an alkaline earth metal alloy layer. The work function of the second membrane (2) is 2.0 eV to 3.5 eV. The composite membrane electrode having a work function gradient has extremely great stability and effectively increases the service life of the component. The work function of the second membrane (2) is merely 2.0 eV to 3.5 eV, an organic/metal interface barrier is effectively reduced. At the same time, the structure of the composite electrode having the work function gradient gradually reduces an electron injection barrier, orderly guides an electron injection, and increases the luminous efficiency of the component.
