Abstract: In the present work, at first, the metal complexes [Os^II (phen) ₂ (phen-dione)](PF₆)₂.2H₂O, [Os^II (phen)(bpy) (phen-dione)](PF₆)₂.2H₂O and [Os^II (bpy)2(phen-dione)](PF₆)₂.2H₂O, (phen = 1,10-phenanthroline, bpy = 2,2^/: bipyridil and phen-dione = 1,10-phenanthroline-5,6-dione) have been synthesised as photo sensitizers for TiO₂ semiconductor solar cells. Then, we have synthesised the TiO₂ nanoparticle with ascorbic acid as the reducing agent. The particle size of TiO₂ nanoparticle has been obtained about 20 nm. The optimum reaction conditions and the product obtained have been reported. At last, the reactivity and coordination between prepared TiO₂ thin film and complexes have been studied. It was found that coordination between phen-dione complexes and TiO₂ increases the intensity of electronic absorption. The surface topography and grain size of TiO₂ nanoparticle and thin films were characterised and analysed with atomic force microscopy (AFM). Also, the products have been characterised by IR and UV-Vis spectroscopy. The structures of products were characterised by XRD. The reaction details and features were described and discussed.
