摘要

紫外有机发光器件(OLED)的宽带隙发光分子限制了空穴注入效率，从而导致载流子复合低效，器件发展受限。可溶液处理工艺兼顾了低成本、高可控性及规模生产的时代特色。本文报道了利用溶液法制备的WCl

及其与聚(3

4-乙烯二氧噻吩)-聚苯乙烯磺酸掺杂复合物(PEDOT∶PSS+WCl

)调控近紫外OLED的空穴注入特性，实现了高效率近紫外有机发光。X射线光电子能谱、紫外-可见光吸收光谱等分析表明，WCl

和PEDOT∶PSS+WCl

薄膜具有优异的电子特性和光透过性。伏安特性和阻抗谱分析表明，空穴注入能力按WCl

、PEDOT∶PSS和PEDOT∶PSS+WCl

的顺序依次增强。以PEDOT∶PSS+WCl

作空穴注入层、2-(4-联苯)-5-(4-叔丁基苯基)-1

4-恶二唑(PBD)作发光层，获得了最大外量子效率为2.6%、最大辐照度为8.05 mW/cm

、半峰宽为45 nm、电致发光峰为405 nm的高效率近紫外OLED。器件寿命测试对比结果表明，WCl

掺杂PEDOT∶PSS后器件的稳定性得到了增强。该研究结果拓展了WCl

的应用领域，对于推进高效稳定近紫外OLED的进一步发展具有一定的借鉴意义。

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

and its doping composite of poly(3

4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT∶PSS)+WCl

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

and PEDOT∶PSS+WCl

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

PEDOT∶PSS and PEDOT∶PSS+WCl

. Using PEDOT∶PSS+WCl

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

4-oxadiazole(PBD) as emissive layer

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

doped PEDOT∶PSS considerably enhances the stability of near UV-OLED. Our results expand the application of WCl

and efficient stable near UV-OLED.
