Description 734-741
The aim of this study is to investigate how the materials synthesized by both methods affect the luminescence and
electrical properties. Also, another purpose is to examine the effect of doping types on optics and conductivity. At the end of
the synthesis, X-Ray diffractometer (XRD) was used to examine the crystal structure and the possible different phases that
may occur, Raman spectroscopy analysis was used to obtain information about the symmetry properties of the formed
structure and the appearance of different vibration modes and the degradation (defect) formed in the structure.
Photoluminescence (PL) Spectroscopy measurements at room temperature were employed. The peaks in the excitation
spectrum at approximately 446 nm (5I8 → 5G6) correspond to the 4f-5d transition of the Ce3 + ion. Specific surface area
analysis was performed using Brunauer-Emmett-Teller (BET). FE-SEM image was taken for morphological analysis of the
structure. The ionic conductivity of the pelletized powder ceramic undoped CeO2 and La3+, and Ho3+ doped CeO2 electrolyte
was measured by impedance spectroscopy. The temperature value of the Ce0.85La0.10Ho0.05O2 sample synthesized by the high
conductivity hydrothermal method was found as 5.64x10-3 Ω.cm-1 at 750 with the best conductivity result.
