| titleOfInvention | Organic electroluminescence device and preparation method thereof |
| abstract | An organic electroluminescence device comprises an anode, a hole injection layer, a hole transport layer, a luminescent layer, an electron transport layer, an electron injection layer and a cathode which are stacked in sequence, wherein the electron injection layer consists of a rubidium compound doped layer and a metal doped layer; the rubidium compound doped layer comprises a rubidium compound material and a metal material I doped in the rubidium compound material; the rubidium compound material is at least one of rubidium carbonate, rubidium chloride, rubidium nitrate and rubidium sulfate; the work function of the metal material I is -2.0 eV to -3.5 eV; the metal doped layer comprises a metal material II and a lithium salt material doped in the metal material II; the work function of the metal material II is -2.0 eV to -3.5 eV; the lithium salt material is at least one of lithium oxide, lithium fluoride, lithium chloride and lithium bromide. The organic electroluminescence device is relatively high in luminescence efficiency. The invention further provides a preparation method of the organic electroluminescence device. |
