Applications
Bis(2,4-difluorophenylpyridinato)-tetrakis(1-pyrazolyl)borate iridium(III), FIr6, is commonly used as a blue emitter material for OLED devices.
In terms of colour purity and quality, FIr6 is more practical for use in full-colour display devices and lighting applications compared to the more widely-used blue phosphorescent emitter, FIrPic. FIr6 shows deeper blue emissions with major vibronic peaks at 458 and 489 nm, while FIrPic has major vibronic emission peaks at 475 and 500 nm.
