Organic EL devices using a gallium complex
Details
A gallium complex (GaMq_2Cl) consisting of two 2-methyl-8-hydroxy-quinolines (Mq) and a chlorine was synthesized and used for the fabrication of organic EL devices. The photoluminescent peak of GaMq_2Cl at 492 nm was as strong in intensity as that of tris(8-hydroxyquinolinato)aluminum (Alq_3). The organic EL devices using GaMq_2Cl as an emitting material showed green luminance of 10, 490 cd/m^2. When it was used as an electron transport material in a rubrene doped device, an organic EL device with a high luminance of 27, 700 cd/m^2 was obtained.
