摘要

Hybrid inorganic/organic white organic light emitting diodes (hybrid-WOLEDs) are fabricated by combining the blue phosphorescent organic light emitting diodes (PHOLEDs) with red Sr

SiO

:Eu

phosphor spin coated as a color conversion layer (CCL) over the other side of glass substrate on the devices. The basic configuration of the PHOLEDs consists a host material

N'-dicarbazolyl-3

5-benzene (mCP) which doped with a blue phosphorescent iridium complexes iridium(Ⅲ)bis[(4

6-di-fluorophenyl)-pyridinato-N-C2'](FIrpic) to produce high efficient blue organic light emitting diodes. The hybrid-WOLED shows maximum luminous efficiency of 22.1 cd/A

maximum power efficiency of 11.26 lm/W

external quantum efficiency of 10.2% and CIE coordinates of (0.32

0.34). Moreover

the output spectra and CIE coordinates of the hybrid-WOLED have a small shift in different driving current density

which demonstrate good color stability.
