Abstract

The electrochemistry, electroluminescent, and photophysics properties of an efficient blue- and white-emitting electrophosphorescent device, which is based on platinum(II)[1,3-difluoro-4,6-di(2-pyridinyl)benzene] chloride (Pt-4), were analyzed. The investigation revealed that Pt-4 device exhibited narrow emission spectra in the range of 470-520nm that makes it very suitable for applications in blue organic light-emitting diodes (OLED). The device also showed lower current density at the same driving voltage, which can imply that Pt-4 works as a more effective carrier trap in 26m CPy than FPt. The device also offered peak external quantum efficiency (EOE) of 16%, power efficiency of 20 lm W -1, and Commission Internationale d'Énclairage (CIE) coordinates of (0.15, 0.26) that suggests that the utilization of Pt complexes is a viable approach for the development of blue OLEDs.
