Abstract
Metal-chelate complexes have been intensively investigated as an emitting layer and recognized to have excellent electroluminescence (EL) properties. Beryllium complexes such as BeBq(2) and BeMq(2) are known to be green-light emitting materials. Tn this study, the EL characteristics of co-deposited films of BeBq(2) and BeMq(2) was investigated using a device structure of ITO/TPD/BeBq(2):BeMq(2)/Al. The brightness and luminescence of the co-deposited films of BeBq(2) and BeMq(2) were improved by a factor of 1.5 similar to2 in comparison with a device structure of ITO/TPD/BeBq(2) or BeMq(2)/Al.
