Application
The purpose of Acetylacetonatobis(2-phenylpyridine)iridium is to serve as a highly effective dopant and emitter in green phosphorescent OLED devices, enabling substantial brightness levels and impressive quantum efficiencies. This compound is renowned for its substantial role in enhancing device performance, achieving a remarkable brightness of 130,800 cd/m² at a current density of 1550 mA/cm², coupled with a high quantum efficiency range of 15 to 16%. Its utility extends to improving external quantum efficiencies and luminous power efficiencies when integrated into specific host materials, such as 3,5-Diphenyl-4-(1-naphthyl)-1H-1,2,4-triazole (TAZ), due to its nearly perfect internal phosphorescence efficiency and optimal charge injection balance. Additionally, its molecular orientation, favoring alignment parallel to the substrate, further distinguishes it by surpassing the external quantum efficiency performance of similar materials, thereby bolstering its status as a cornerstone material in OLED technology development.
