Abstract

Long-term chemical stability of organometallic reagents incorporated into polydimethylsiloxane matrix of polymer-clad optical fibres by soaking method is investigated by means of VIS/NIR absorption spectroscopy, proton-induced X-ray emission and electron paramagnetic resonance spectroscopy. Based on the obtained experimental results, a modified procedure of sensing coatings preparation is proposed leading to significantly reduced decay of optical properties with time and allowing thus fabrication of practically applicable long sensing fibres.
