Embodiment 1
[0029] This embodiment provides an electrode, such as figure 1 As shown, it includes a first conductive layer 1 and a second conductive layer 2 stacked. The first conductive layer 1 is an Ag layer with a thickness of 16 nm; the second conductive layer 2 is a Yb and Mg alloy layer with a volume ratio of Yb and Mg of 1:1 and a thickness of 2 nm.
[0030] This embodiment also provides an organic electroluminescence device, the device structure is:
[0031] ITO(40nm) / HATCN(10nm) / NPB(110nm) / TCTA(20nm) / CBP(30nm):Ir(ppy) 3 (12%) / BCP(10nm) / Alq 3 (20nm) / Yb(10A):Mg(10A) / Ag(16nm).
[0032] Wherein, the first electrode is an ITO layer;
[0033] The hole injection layer is a HATCN (2,3,6,7,10,11-hexacyano-1,4,5,8,9,12-hexaaza) layer;
[0034] The hole transport layer is an NPB layer;
[0035] The main material layer is a 4,4',4'-tris(carbazol-9-yl)triphenylamine layer;
[0036] The light-emitting layer is Ir(ppy) 3 A doped layer of (three (2-phenylpyridine) iridium (III)) and CBP (...
Embodiment 2
[0043] This embodiment provides an electrode, the structure of which is the same as that of Embodiment 1, the only difference is that the thickness of the second conductive layer is 4 nm.
[0044] This embodiment also provides an organic electroluminescence device, the structure of which is the same as that of Embodiment 1, except that the second electrode is the electrode described in this embodiment.
Embodiment 3
[0046] This embodiment provides an electrode, the structure of which is the same as that of Embodiment 1, except that the thickness of the second conductive layer is 0.5 nm, and the thickness of the first conductive layer is 10 nm.
[0047] This embodiment also provides an organic electroluminescence device, the structure of which is the same as that of Embodiment 1, except that the second electrode is the electrode described in this embodiment.
