Abstract:

We have demonstrated a highly efficient blue phosphorescent organic light emitting diodes (PHOLED) using iridium (III) bis[(4,6-di-fluoropheny)-pyridinato-N,C2] picolinate doped in double emitting layers (D-EML), N,N-dicarbazolyl-3,5-benzene (mCP) and p-bis (triphenylsilyly)benzene (UGH2). D-EML layers were employed to broaden the exciton formation zone and confine excitons. The optimized blue PHOLEDs having mCP/UGH2 as D-EML with a thickness of 200/100 Å, exhibited a peak external quantum efficiency of 11.44%, power efficiency of 16.8 lm/W, luminous efficiency of 23.14 cd/A, and Commission Internationale de I'Eclairage coordinates of (0.17, 0.33).
