Abstract
An organic electroluminescent device (OELD) is provided. The OELD includes a substrate, an anode, a cathode, a hole transport layer, an electron transport layer and an emission layer. The anode and the cathode are disposed on the substrate. The hole transport layer is disposed between the anode and the cathode. The electron transport layer is disposed between the hole transport layer and the cathode. The emission layer is disposed between the hole transport layer and the electron transport layer. The emission layer includes a host and a dopant. The chemical structure of the dopant is shown as the formula [I]: 'M' is a metal atom whose atomic weight is greater than 40. 'S' is selected from a group consisting of alkyl, alkoxy, haloalkyl, halogen, hydrogen and any other substituents.
