OLEDs are nowadays the most important type of light source for artificial lighting, making them potential candidates in the development of full-color flat panel display devices. Challenging problems to be addressed are emission color, emission efficiency and device lifetime. The emission color problem results from the broad emission bands exhibited by electroluminescent devices containing organic emitting layers, since pure and sharp emission bands from these materials, a requisite for display applications, are... [Pg.161]
