||Effect of deposition rate of host material N,N’-dicarbazolyl-3,5-benzene(mCP) in phosphorescent organic light-emitting diodes|
|Date of Defense
||Phosphorescent organic light-emitting diodes (PhOLED) have attracted a lot of attention in these years.Blue PhOLED is especially important because of short lifetime and low optoelectronic performance as comparing to red and green PhOLEDs.Researches have shown that performance of OLED devices is highly rely on the deposition rate of organic materials ,which attest the morphology of organic layers.|
To study how the deposition rate of host material on the performance of blue PhOLED,mCP is chosen a host material for a blue dopant - FIrpic and deposition rate of mCP on the performance of blue PhOLED performance is studied.
It was found that UV-Vis spectrum of mCP varied with different deposition rate.Additionally,an PL emission peak (400nm~500nm) appeared on the thermal evaporated mCP,which was possibly originated from the aggregation of mCP.Surface roughness of the evaporated mCP film became smaller as the deposition rate increased.A high performance (8.52 lm/W@1.2mA/cm2) is fabricated at a deposition rate at 3 A/s.
