- Аннотация: In this work, the optical characteristics and conductivity under photoactivation with visible light of hybrids based on nanocrystalline SnO2 or In2O3 semiconductor matrixes and heteroleptic Ru(II) complex were studied. The heteroleptic Ru(II) complexes were prepared based on 1H-imidazo[4,5-f][1,10]phenanthroline and 2,2’-bipyridine ligands. Nanocrystalline semiconductor oxides were obtained by chemical precipitation with subsequent thermal annealing and characterized by XRD, SEM and single-point BET methods. The heteroleptic Ru(II) complexes as well as hybrid materials were characterized by time-resolved fluorescence and X-ray photoelectron spectroscopy. The results showed that the surface modification of SnO2 nanoparticles with heteroleptic ruthenium complexes led to an increase in conductivity upon irradiation with light appropriate for absorption by organometallic complex. In the case of In2O3, the deposition of Ru (II) complexes resulted in a decrease in conductivity, apparently due to the special structure of the surface layer of the semiconductor.
