Paper Abstract

The luminescent properties of organic infrared (IR) and near-infrared (NIR) light-emitting materials were investigated for optical communication applications. These materials consisted of two organic ionic dyes, (2-[6-(4-dimethylaminophenyl)-2,4-neopentylene-1,3,5-hexatrienyl]-3-methyl-benzothiazonium perchlorate) (LDS821) and [C41H33Cl2N2]+•BF4- (IR1051), and an organic rare-earth complex, erbium (III) tris(8-hydroxyquinoline) (ErQ). The three materials are both photoluminescent and electroluminescent in the 0.8-, 1.1- and 1.5-μm wavelength regions, respectively, and so can be used as optically active species in devices operated by either optical or current excitation. Three device forms were fabricated with these light-emitting materials as optically active species, namely vacuum-deposited or spin-coated polymer thin-films, monodispersed polymer microparticles and embedded polymeric optical waveguides. Their luminescent processes are discussed and possible optical communication applications are proposed.
