ELECTROLUMINESCENT DEVICES WITH MIXED ELECTRON TRANSPORT MATERIALS |
摘要 |
<p>An OLED device comprises a cathode, an anode, a light emitting layer, and on the cathode side of said emitting layer, a further layer containing a) a first compound that has the lowest LUMO value of the compounds in the layer, in an amount greater than or equal to 10% by volume and less than 100% by volume of the layer; b) at least one second compound exhibiting a higher LUMO value than the first compound, where at least one of the second compounds is a low voltage electron transport material, the total amount of such second compounds(s) is less than or equal to 90% by volume of the layer; and c) a metallic material based on a metal having a work function less than 4.2 eV.</p> |
