Abstract
Pulsed laser deposition is used to deposit organic thin films, in particular of materials that are of interest to display applications. Luminescent films such as tris-(8-hydroxyquinoline)aluminum (Alq3 ) can be deposited without degradation of their luminescent properties. Alternating layers of different materials, one of which is an organic compound and another of which is an inorganic material, can be deposited using this method. High luminescent efficiency multi-layer films can be obtained.
