Abstract: A hybrid LED-OLED lighting device includes a waveguide layer, a light-emitting diode (LED) array optically coupled to the waveguide layer, and an organic light-emitting diode (OLED) array. Light emitted from the LED array is provided to an edge of the waveguide layer and light emitted from the OLED array is provided to a first surface of the waveguide layer. Light emitted from the LED array and light emitted from the OLED array passes through a second surface of the waveguide layer opposite the first surface of the waveguide layer, and light emitted from the lighting device comprises the light emitted from the LED array and the light emitted from the OLED array.

Abstract: A series of functionalized imidazophenthridine analogue-based blue phosphorescent emitters have been designed, where bulky substituents (e.g., tetrabutyl, phenyl, mesityl, triisopropylbenzene, etc.) are introduced on an imidazophenthridine fragment of the emitters. Bulky substituents may suppress potential excimer formation, as well as improve the solubility of the complexes. This class of emitters may be utilized in luminescent labels, emitters for organic light emitting devices, and lighting applications.
