Abstract: Organo-transitional metal compounds have been of particular interest for Organic Light Emitting Diode (OLED) application in the last few decades due to their high efficiencies. Due to a process called triplet harvesting, the efficiency can be as high as 100%. It is very likely that within some years, large flat panels and also small-size displays will be available. In this work, we report on the characteristic behaviors of the famous triplet emitter tris[2-(2-pyridinyl)phenyl-C,N]-iridium (Ir(ppy)3). OLED devices with the Emitting Layer (EML) consisting of Ir(ppy)3 doped in 4,4’-N,N’-dicarbazole-biphenyl (CBP) were fabricated, and the summary of the fabrication process will be discussed. Application of pulsed electric field to the OLED device was realized using pulse generator. The establishment of the innovative data acquisition setup using the streak camera coupled with the monochromator makes possible to obtain several information of the emission properties of the sample simultaneously. In the end, the summary and future developments of this work will be discussed. ii
