THIN-FILM ORGANIC LIGHT-EMITTING DEVICES AND LASERS

We describe recent advances in luminescent devices based on Forster en ergy transfer in vacuum deposited, small molecular weight organic thin films. As examples, we concentrate our discussion on a novel, 12 laye r stacked organic light emitting device useful for full color, high re solution flat panel display applications, and optically pumped semicon ducting organic thin film lasers. Both devices demonstrate the unusual properties characteristic of these materials which open the door to a wide range of new device possibilities. (C) 1998 Elsevier Science B.V .
