Embodiment Construction
[0022] see figure 1 , the embodiment of the diode of the present invention includes a cathode 11 and an anode 13, wherein the cathode 11 is arranged opposite to the anode 13; the electron transport layer 12 is arranged between the cathode 11 and the anode 13, and the electron transport layer 12 is doped with an alkali as an electron injection layer Metal compounds, wherein the alkali metal compound as the electron injection layer includes lithium metaborate (LiBO 2 ), potassium silicate (K 2 SiO 3 ), four (8-hydroxyquinoline) boron lithium (Liq), alkali metal acetate at least one substance, the alkali metal acetate can be lithium acetate (CH 3 COOLi), sodium acetate (CH 3 COONa), potassium acetate (CH 3 COOK), rubidium acetate (CH 3 COORb), cesium acetate (CH 3 COOCs) at least one substance.
[0023] For example, the alkali metal compound is LiBO 2 , or K 2 SiO 3 and CH 3 COOLi, or Liq, CH 3 COONa and K 2 SiO 3 ..., can be combined arbitrarily according to actual...
