Title
Effect of type-II quantum well of m-MTDATA/alpha-NPD on the performance of green organic light-emitting diodes
Abstract
The type-II multiple quantum well (MQW) structure is prepared and introduced into green organic green light-emitting diodes consisting of 4,4′-bis-[N-(naphthyl)-N-phenyl-amino]biphenyl (α-NPD) and tris-(8-hydroxyquinolinato)-aluminum (Alq3). The quantum well (QW) and wall are fabricated by 4,4′,4″-tris-(3-methylphenylphenylamino)triphenylamine (m-MTDATA) and α-NPD, respectively. The device performance of MQW organic light-emitting diodes (OLEDs) has been improved; the luminous efficiency by 25% and power efficiency by 17% compared with the reference device. The performance improvement can be explained by the increased electron–hole balance in the device due to the hole confinement in the QW structure.
