Abstract: Photoluminescence(PL) and electroluminescence(EL) properties of a samarium complex Sm(DBM)phen(DBM=dibenzoylmethane, phen=1,10-phenanthroline) were investigated. A series of devices based on Sm(DBM)phen were fabricated. The results show that Sm(DBM)phen owns good electron injecting and transporting properties. By optimizing the device structure, bright efficient orange EL devices could be achieved, and the maximum brightness and efficiency were 150 cd/m2 and 0.72 cd/A, respectively. The device showed the characteristic emission peaks of the Sm3+ ion at all operating voltages. It was noticed that the relative intensity of Sm3+ emission peaks differed from each other in PL and EL cases, which could be ascribed to the change of coordination sites of the Sm3+ ion during the evaporation of the samarium complex in the EL case.

Key words: Samarium complex, Photoluminescence, Electroluminescence
