[ 1 ] - بررسی خواص ترمولومینسانس نانوساختار هیدروکسی اپتایت آلاییده با یوروپیوم
Nano-structured hydroxyapatite doped with europium in different mole percentages of 1 to 5 have been synthesized using a hydrolysis route. Structural and thermoluminescence (TL) properties of the samples have been discussed in detail. Powder X-ray diffraction and scanning electron microscopy confirm the phase purity and nano structure nature of synthesized powder. The samples were irradiated by...
[ 2 ] - تأثیر عملیات پخت بر پاسخ ترمولومینسانس هیدروکسی اپاتیت نانوساختار فراهمشده به روش هیدرولیز از دیدگاه دزیمتری
In this study, the pure nano-structure hydroxyl apatite samples were synthesized via hydrolysis method. The powder samples were sintered at various temperatures of 500°C, 700°C and 900°C in a furnace. X-ray diffraction (XRD) and Fourier transform infra-red (FTIR) spectroscopy systems were used to characterize the synthsized samples. Comparison of the glow curves shows that the most ...
[ 3 ] - Study on Effects of Hydroxyapatite Synthesis Conditions Using Hydrothermal Method on its Thermoluminescence Response from Dosimetry Viewpoint
In the current research, hydroxyapatite samples, synthesized by hydrothermal methods was studied from the perspective of thermoluminescence dosimetry. The results of the study were compared and studied with different aspects of dosimetry, including dose-response variations of synthesized samples, degree of its linearity, and the percentage of response fading, as well as the position of the main...
