Low roll-off efficiency and chromatic-stable White Organic Light-Emitting diodes based on excimer emission

摘要：

White Organic light emitting devices (WOLEDs) based on excimer emission have been fabricated, using only a platinum 1,3-difluoro- 4,6-di(2-pyridinyl)benzene chloride(Pt-4) doped in l,3-bis(9-carbazolyl)benzene (mCP), a single emissive layer to obtain white emission which comprises red and blue light-emitting spectra. The maximum current-and power- efficiency values of white device are 11.5 cd/A and 9.21 lm/W, respectively. And we obtained low roll-off efficiency and stable Commission International dEclairage (CIE) chromaticity coordinates of (0.32, 0.39).
