Nanomalzemelerin sentezi ve [Ru(bpy)3]2+ kompleksi ile birlikte sensör özelliklerinin araştırılması

In this study, optical properties of tris(2,2-bipyridyl)ruthenium (II) chloride ([Ru(bpy)3]2+), a ruthenium complex, together with various nanoparticles (TiO2 and core-shell TiO2@Ag nanoparticles) were investigated in the oxygen-permeable polymeric material. Plasticizer containing polymethylmethacrylate (PMMA) was shaped in form of thin film by applying the spin coating process and its optical properties and sensitivity towards oxygen were observed. It is known from previous studies that the [Ru(bpy)3]2+ complex exhibits extraordinary optical properties and high oxygen sensitivity when embedded in the above-mentioned matrix and used in combination with silver nanoparticles. In our thesis, the presented design is totally different from the earlier published literature. The porous and straight thin composite films were fabricated via the spin coating technique. Unlike the previous studies, the semiconductor TiO2 and core-shell TiO2@Ag nanoparticles were doped into these composite materials and the spectral properties of the prepared thin films were examined. Luminescence signal variations resulting from the application of oxygen sensor at 626 nm were recorded.
