Optical properties of poly(p-phenylenevinylene) periodic multilayer structures fabricated by self-assembly method and its light-emitting devices with microdisk geometry

Periodic multilayer structures of poly(p-phenylenevinylene)s have been fabricated by a self-assembly method on quartz or indium-tin- oxide-coated glass substrates. Alternating multilayers consisting of poly(P-phenylenevinylene) (PPV) and PPV derivatives which possess polyanion properties were adsorbed onto positively charged substrates. Periodic multilayers with a microdisk geometry have also been fabricated on quartz or indium-tin-oxide-coated glass substrates, and the optical properties and a yellow electroluminescence from a light- emitting device with a microdisk geometry have been studied.
