Abstract
Wide bandgap of emissive molecule in ultraviolet organic light-emitting device(UV-OLED) restricts hole injection
which results in inefficient carrier recombination and counteracts performance promotion. Solution-processed techniques with low cost
fine tunability and high throughout production meet the current requirement of manufacture. Herein
solution-processed WCl
6
and its doping composite of poly(3
4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT∶PSS)+WCl
6
are employed for tailoring hole injection of near UV-OLED
and thus achieving high efficiency. X-ray photoelectron spectroscopy and UV-visible absorption analysis show that WCl
6
and PEDOT∶PSS+WCl
6
films behave exceptional electronic properties and superior optical transmittance. Current-voltage characteristics and impedance spectroscopy analysis confirm that the hole injection ability is enhanced in the order of WCl
6
PEDOT∶PSS and PEDOT∶PSS+WCl

. Using PEDOT∶PSS+WCl

as hole injection tailoring and 2-(4-biphenyl)-5-(4-tert-butylphenyl)-1

the near UV-OLED reaches maximum external quantum efficiency of 2.6%
radiance of 8.05 mW/cm

full width at half maximum of 45 nm and electroluminescent peak of 405 nm. Device aging tests indicate that WCl
6
doped PEDOT∶PSS considerably enhances the stability of near UV-OLED. Our results expand the application of WCl
6
and efficient stable near UV-OLED.
