Preparation and characterization of Rhodamine B and Alq3 thin films deposited by solution jet beam method

We report the solution jet beam method as a novel technique to fabricate organic thin films in vacuum. The method can be applied even to ionic organic materials, which cannot be vacuum evaporated due to thermal decomposition. Thin films of RhB (Rhodamine B) and Alq3 (tris(8-hydroxyquinoline)aluminum) were fabricated and characterized. Organic light emitting diodes (OLEDs) were also fabricated using Alq3 films prepared by this method.
