    (POLISH ACAD SCIENCES INST PHYSICS, 2016) Bezir, N. Cicek; Evcin, A.; Kayali, R.; Ozen, M. Kasikci; Esen, K.; Cambaz, E. B.
    Zirconium oxide (ZrO2) is one of the widely studied oxide materials because of its excellent electrical, mechanical and optical properties. In this study, undoped and Dy-Eu-Ce co-doped ZrO2 nanofibers were fabricated by electrospinning method and their crystal structure, surface morphology, optical properties, electrical and electronic properties, and chemical properties have been analyzed using X-ray diffraction, scanning electron microscope (SEM), UV/VIS spectrometer, four point probe technique ( FPPT) energy dispersive X-ray (EDX) measurements, respectively.

    Comparison of Five-Layered ZrO2 and Single-Layered Ce, Eu, and Dy-Doped ZrO2 Thin Films Prepared by Sol-Gel Spin Coating Method
    (Polish Acad Sciences Inst Physics, 2017) Bezir, N. Cicek; Evcin, A.; Kayali, R.; Ozen, M. K.; Esen, K.
    In order to investigate the influence of the number of layers on the properties of ZrO2 thin films, we prepared one pure ZrO2 film sample with five layers and Ce, Eu, and Dy-doped ZrO2 samples with single layer, by spin-coating sol gel-method. The crystal structures of thin films were determined using X-ray diffraction, morphology of the samples was analyzed by scanning electron microscopy, and the optical properties of the samples were determined by ultraviolet/visible absorbance measurements. The results of these measurements have shown that the concentration of the dopants and the thickness of thin film layers play a vital role in the physical, chemical, and optical properties of the pure and doped ZrO2 thin films.
