Organic light-emitting diodes (OLEDs) have rapidly grown as one of the leading
technologies for full-color display panels and eco-friendly lighting sources due to their …

White organic light‐emitting devices (WOLEDs) have advanced over the last twelve years to
the extent that these devices are now being considered as efficient solid‐state lighting …

Abstract Light-emitting diodes (LEDs), which convert electricity to light, are widely used in
modern society—for example, in lighting, flat-panel displays, medical devices and many …

Organic light-emitting diodes are a major driving force of the current information display
revolution due to their low power consumption and potentially long operational lifetime …

Organic light-emitting diodes (OLEDs) with thick carrier transport layers are desirable for
high production yields of OLED-based displays and lighting; however, high operating …

We demonstrate very high efficiency electrophosphorescence in organic light-emitting
devices employing a phosphorescent molecule doped into a wide energy gap host. Using …

In the preceding paper, Paper I [Phys. Rev. B 62, 10 958 (2000)], we studied the formation
and diffusion of excitons in several phosphorescent guest-host molecular organic systems …

Phosphorescent organic light-emitting diodes (PHOLEDs) feature high efficiency,,
brightness and colour tunability suitable for both display and lighting applications. However …

We demonstrate high-efficiency white organic light emitting devices (WOLEDs) employing
three adjacent phosphorescent emission layers (3-EMLs). The metal-organic dopants for …

We demonstrate high-efficiency organic light-emitting devices employing the green
electrophosphorescent molecule, fac tris (2-phenylpyridine) iridium [Ir (ppy) 3], doped into …
