Özet

TiO2 with high photoactive wide band gap energy semiconductor has been studied intensively for its attractive applications as photo catalyst and solar cell. TiO2 has three kinds of different crystal structures; anatase, brookite and rutile. TiO2-nanoparticles could become valuable light emitting materials when they are doped with highly luminescent rare earth ions. In this study, Dy-Eu-Ag co-doped TiO2 nano particles were prepared by electrospinning method. The crystal structures of nanofibers were determined X-Ray Diffraction device (XRD), morphology of the samples were analyzed by scanning electron microscope (SEM), and the optical properties of the samples were determined by ultraviolet/visible spectrometer (UV/VIS) measurements. Electrical and electronic properties of the sampled were determined using the data obtained from four point prob technique (FPPT).
