Abstract

Hightly efficient blue phosphorescent organic light emitting diodes(OLEDs) based on a host material 1

5-tri(9H-carbazol-9-yl)benzene (TCzP) doped (iridium(Ⅲ) picolinate) (FIrpic) were fabricated

and a double-emitting layer device was also manufactured. The maximum brightness of 11 957 cd/m

peak current efficiency of 18.8 cd/A with Commission Internationale de L'Eclairage (CIE) coordinates of (0.17

0.37) were obtained. The emission peak wavelength of 472 nm with its shoulder peaking at 496 nm were observed. Even at high brightness of 1 000 cd/m

the current efficiency remains 13.5 cd/A. The experimental results indicate that high triplet energy and hole mobility for a host material are very important to achieve highly efficient blue phosphorescent device.
