| Abstract: | High efficiency red organic light-emitting diodes (OLEDs) using tris-(8-hydroxyquinoline) aluminum (AlQ) as host material fabricated via a thermal vacuum deposition process were investigated. Red organic EL devices with the structure of ITO/NPB/AlQ:Rubence(3%):DCM(3%)/AlQ/Mg:Ag/Al with a CIE coordinates of (0.45,0.50),a maximum luminance of 4 330 cd/m2,and a maximum luminance efficiency of 6.77 lm/W have been achieved. |
