Abstract
This article describes our recent progress on the development of organic emissive materials and devices for photonic communication applications. Luminescence properties in the infrared (IR) region were examined for two types of organic emissive material, an organic rare earth complex and an organic ionic dye, and their potential for use as emissive materials in photonic communication applications was discussed. The luminescence mechanism elucidated in this study suggested a guideline for the future development of organic IR emissive materials. Novel organic emissive devices were fabricated by combining organic emissive materials with various types of photonic crystal structure utilizing nanotechnology. These devices utilize the advantages and unique properties of organic materials, and so signal the way towards the breakthroughs needed to realize emissive devices for the photonic communication networks of the future.
