In this study, lithium triborate (LiB3O5) doped with different metal oxides were investigated to explore its thermoluminescence properties. Solid-state reaction method was employed for the synthesis of the desired materials. The formation of the produced phases was confirmed by Powder X-Ray Diffraction (XRD), Infrared (IR), Differential Thermal Analysis (DTA) and Scanning Electron Microscopy (SEM) examinations. It was found that, CuO and Al2O3 doped lithium triborate samples exhibit very significant thermoluminescence glow curves to be promising dosimetric material.

Investigation of bismuth doped bioglass/graphene oxide nanocomposites for bone tissue engineering
Pazarçeviren, Ahmet Engin; Tezcaner, Ayşen; Keskin, Dilek; Evis, Zafer (2018-03-01)
In this study, bismuth doped 45S5 nanobioactive bioglass (nBG) and graphene oxide (GO) nanocomposites were developed and characterized in terms of microstructural, mechanical, bioactivity and biological properties. Bismuth (Bi) - doped nBG was synthesized by sol-gel method and sintered at 600 degrees C for 2 h. Nanosized GO was homogeneously mixed with Bi doped bioglass at various ratios to prepare nanocomposites. Addition of Bi increased the density of nBG samples while a considerable decrease in density w...
An investigation of the microstructural and mechanical properties of tri-calcium phosphates doped with aluminum and fluoride ions
Tahmasebifar, Aydin; Evis, Zafer; Department of Engineering Sciences (2011)
The aim of this study was to investigate the microstructure and mechanical properties of pure tricalcium phosphate (TCP) and tricalcium phosphates doped with aluminum (Al3+) and fluoride (F-) ions at different compositions. TCP was synthesized via precipitation method and sintered at 1100C for 1 and 5 h. It was observed that density and relative density of the sintered materials were decreased by extending the sintering time. Increased densities were achieved upon Al3+ and/or F- doping. For structural anal...
Determination of trapping parameters of thermoluminescent glow peaks of semiconducting Tl2Ga2S3Se crystals
IŞIK, MEHMET; YILDIRIM, TACETTİN; Hasanlı, Nızamı (2015-07-01)
Thermoluminescence (TL) properties of Tl2Ga2S3Se layered single crystals were researched in the temperature range of 290-770 K. U glow curve exhibited two peaks with maximum temperatures of similar to 373 and 478 K. Curve fitting, initial rise and peak shape methods were used to determine the activation energies of the trapping centers associated with these peaks. Applied methods were in good agreement with the energies of 780 and 950 meV. Capture cross sections and attempt-to-escape frequencies of the trap...
Investigation of the performance of colloidal LiFePO4 particles in suspension flow battery
Yıldız, Bayram; Aşkar, Yasemin; Coşkun, Elif; Maviş, Bora; Çınar, Simge (2021-06-12)
In this study, colloidal LiFePO4 particles were synthesized through solvothermal route. Effect of solvothermal method parameters on formation of colloidal LiFePO4 was investigated. Post-processing treatments were found effective to obtain non-aggregated colloidal particles. The rheological behavior of aqueous suspensions including electroactive material was examined in terms of salt, electroactive material concentration and carbon content. A three-electrode systems was used to analyze electrochemical perfor...
An investigation of microstructure, microhardness and biocompatibility characteristics of yttrium hydroxyapatite doped with fluoride
Toker, Sıdıka Mine; Evis, Zafer; Department of Biomedical Engineering (2010)
The aim of this study was to investigate the microstructure, microhardness and biocompatibility properties of nano hydroxyapatite (HA) doped with a constant yttrium (Y3+) and varying fluoride (F-) compositions. HA was synthesized via precipitation method and sintered at 1100C for 1 hour. Increased densities were achieved upon Y3+ doping while F- doping led to a decrease in densities. For structural analysis, XRD, SEM and FTIR spectroscopy examinations were performed. No secondary phases were observed in XR...
