A method for vaporizing organic materials onto a surface, to form a film includes providing a quantity of organic material in a fluidized powdered form; metering the powdered organic material and directing a stream of such fluidized powder onto a first member; heating the first member so that as the stream of fluidized powder is vaporized; collecting the vaporized organic material in a manifold; and providing a second member formed with at least one aperture in communication with the manifold that permits the vaporized organic material to be directed onto the surface to form a film.
