A unique point OLED source

Highly luminous polymers have been successfully prepared by copolymerization of various arylene vinylene units. Among the copolymers synthesized, poly(phenylene vinylene) (PPV) and its derivatives have been studied most intensively because they show fairly strong fluorescence and have a wide structural variety. In this paper, light-emitting polymers and traditional organic LED technology are briefly reviewed at first. A novel and unique point source based on the organic LED fabricated on an optical fiber is then proposed. As proof of concept, some preliminary experimental results are shown. Two light-emitting materials needed for our experiments are synthesized. It is illustrated that the unique point OLED source is feasible, which can lead to many practical applications, such as biomedical imaging.
