Abstract

Effects of hole injection layer on the luminescent properties of white-light organic light-emitting diodes have been systematically investigated. Evidence showed that by adding m-MTDATA as the hole injection layer the brightness of the white-light OLEDs could be significantly improved. At an effective hole injection assistance by a 650-Å-thick m-MTDATA, a brighter and high purity white-light organic light-emitting diode could be realized by using a 20-Å-thick Anthracene:DCM2 red-emitting layer, associating a 280-Å-thick undoped Anthracene blue-emitting layer.
