Microring light-emitting devices with self-assembled multilayer structures based on poly( p-phenylene vinylene)s

Abstract

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) and poly(p-phenylene vinylene) have been adsorbed onto the positively charged substrates and the optical properties have been studied. The periodic multilayers with microring geometry have also been fabricated around the quartz fibers, and the optical properties and yellow electroluminescence from a light-emitting device with microring geometry have been investigated.
