Optical Properties Of Self-Assembled Thin-Film Of Poly(P-Phenylene Vinylene)S And Its Application To Light-Emitting Devices With Microring Geometry

Periodic multilayer structures of poly(p-phenylene vinylene)s have been fabricated by a self-assembly method on flat surfaces and round surfaces of optical fibers. Alternating multilayers consisting of poly{1,4-[2-(5-carboxypentyloxy)-5-methoxyphenylene]vinylene} (CPMOPPV) and poly(p-phenylene vinylene) (PPV) were adsorbed onto the positively charged substrates. The optical properties of the periodic multilayer structures of CPMOPPV/PPV have been studied. Periodic multilayers with microring geometry have also been fabricated around the quartz fibers. Their optical properties have been studied, and yellow electroluminescence from a light-emitting device with microring geometry has been observed. (C) 2000 American Institute of Physics.
