“…They were found to be linear between 0.08 and 5.33 Gy [2]. Rao et al, (1992) reported using various magnesium salts such as Mg(NO3)2 and their combination with magnesium oxide in a presence flux. They studied their emission characteristic.…”

“…It has a melting point of ~ 2850 o C. It has a single phase, with rock salt structure (fcc) like oxides of other alkaline earth metals, cubic structure with lattice parameters a=b=c 4.23 Å. MgO ceramic is one of the investigated host materials in radiation dosimetry. But pure MgO does not exhibit high luminescence TL sensitivity to ionizing radiation, so researchers have been synthesized it with various dopants to improve the radiation sensitivity [1][2][3][4][5][6]. In the literature, there are many synthesis methods such as solution combustion, precipitation sol-gel, solid-state., etc.…”

“…Structural characterization produced materials studied with XRD analysis. The emission spectra of Tb doped MgO as six peaks have been recorded [6]. Recently, Mokokeng et al, (2020) reported the thermoluminescence properties of MgO:Al,Li synthesized by microwave-assisted solution combustion synthesis.…”

In this study, undoped MgO and titanium (Ti 4+ ) doped MgO ceramics were synthesized using the solid state-assisted solution combustion synthesis method. The structural characteristics were investigated using X-ray diffraction (XRD) and scanning electron microscope (SEM). TL curves of the MgO:Ti 4+ (0.1%wt) ceramic consist of three TL peaks located at 70, 250 and 290 o C with a heating rate of 2 o C/s after 1 Gy beta dose. Radioluminescence (RL) characteristic of the MgO:Ti 4+ (0.1%wt) ceramic was studied with excitations between 200 -1000 nm. It was found to be the four emission bands the maximums located at 327 nm (~3.79 eV), 694 nm (~1.78 eV), 715 (~1.73 eV), and 745 (~1.66 eV). Some dosimetric characteristics such as TL curve, reusability, dose-response, of the ceramic were investigated using the thermoluminescence (TL) technique using beta radiation of 90 Sr/ 90 Y. Dose-response characteristics showed the integrated TL signals between 170-350 o C exhibited a linear up to 20 Gy. The experimental results showed that if it is developed of the MgO:Ti 4+ (0.1%wt) ceramic can be considered as a dosimetric material with suitable properties in personal and medical applications.

“…Kao and Chen [1,2] successfully prepared SrIn 2 O 4 :xTb and CaIn 2 O 4 :xTb phosphors by solid-state reactions. In the past also, the luminescence properties of Tb 3+ in different host matrix have been extensively studied [3][4][5]. With Tb 3+ activation, the emission is from 5 D 3 and 5 D 4 states to the 7 F states.…”
