In this study, the bis(8-oxyquinolino)zinc II (Znq$_2$) were synthesized successfully from zinc chloride (ZnC1$_2$) as a initial material. Then, we fabricated red organic electroluminescent device with a dye (DCJTB)-doped and inserted Znq$_2$ between emission layer and cathode layer for increasing EL efficiency. The hole transfer layer is a N,N'-diphenyl-N,N'-bis-(3-methyl phenyl) -1,1'-diphenyl-4,4'- diamine(TPD), and the host material of emission layer is Znq$_2$. And we study the electrical and optical properties of devices. We found that the device using Znq$_2$ inserting layer result in the increased efficiency.
