Abstract
The fluorescent dyes allow new optical applications in polymer-based optical fibre technology. The article presents highly fluorescent 1,4-Bis(2-methylstyryl)benzene doped poly(methyl methacrylate) (PMMA) fibre. The multi-peak (422, 450, 488nm) fluorescence spectrum of the bulk specimen under 355nm excitation is presented. The polymerization and fibre drawing process is also shown. The fluorescent properties vs. fibre length at excitation 405nm are investigated. Significant spectrum shape changes and red shift phenomena of individual peaks are presented using one end excitation and fibre cutting method measurements for fibre length 2–90cm. Obtained attenuation level 0.69dB/m limits useful fibre length but obtained results can be useful in new polymeric fibers applications (e.g. sensors, light sources).
