Abstract
Three different oxygen sensitive nano-materials namely Pt (II) meso-tetra(pentafluorophenyl) porphine (PtTFPP), Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) and Pd (II) meso-tetra (pentafluorophenyl) porphine (PdTFPP) has been coated on one end tip of an optical fiber to form optical fiber dissolved oxygen sensor. The performance in terms of fluorescence intensity when exposed to oxygen at various (gaseous) concentrations between the three optical fiber sensors has been performed. Optical fiber sensor probe coated with PdTFPP exhibits the highest sensitivity while Ru (II) complex coated optical fiber sensor demonstrates the highest linearity of all three nano-materials.
