Abstract
The Bis(8-oxyquinolino) zinc lII (Znq2) were synthesized successfully from zinc chloride as a initial material . The organic electroluminescece devices (ELDs) were fabricated with N-N'-diphenyl-N-N'-bis (3-meth-ylphenyl)-1,1'-biphenyl-4,4'-diamine (TPD) which act as a hole transporting layer and the Znq2 act as an EL emitting layer and electron transporting layer. In order to maximize luminance of ELD, TPD/Znq2/Al were deposited onto cleaned indium tin oxide (ITO) by changing thickness of EL emitting layer. The photoluminescence (PL) results show that Znq2 compound emits yellow green from 540nm. electrochemical behavior with V-J and V-L curve of carrier injection was investigated from 6 V. respectively. The maximum luminance were defected about . From these results, ai synthesized Znq2 material maybe one of the useful material of organic EL display material.
