Scintillation and dosimetric properties of Ce-doped MgAl2O4 single crystals

Synthesis, thermoluminescence characterizations, and photon attenuation parameters of MgAl2O4 structure doped with different ions

“…where B is the average TL background intensity from the nonirradiated chips, σ B [6] is the standard deviation of readout measurements, and f c is the calibration factor that can be found from 1/slope of the readout TL signal as a function of the recorded absorbed dose.…”

“…(eV) values represent the slope of the best-fit lines and s (s À1 ) values were calculated using Equation (6). The obtained values are listed in Table 2.…”

“…There are various radiation regimes in addition to their dose-response curves that can play an important role in TL dosimetry. If the purpose of the TL materials is to monitor and estimate radiation doses absorbed in the tissue or bone of the human body, it is desirable to find bioequivalence TL phosphors that have an effective atomic number (Z eff ) with similar characteristics to that of soft tissue in the human body (Z eff ⁓7.13) or natural bone (11.3-16.5) [6,[8][9][10]. Magnesium aluminate (MgAl 2 O 4 ) phosphor is regarded as a good TL host material with its characteristics of excellent mechanical strength, low thermal expansion coefficient, resistance to ambient conditions, relatively low density, high melting point (⁓2000 C), and a bandgap structure of $7.4 eV [5,[11][12][13][14].…”

“…Storage thermoluminescence phosphors can be used as dosimeters in different applications such as personal and environmental monitoring fields and radiation diagnostics [1][2][3] due to their ability to absorb and accumulate the energy of ionizing radiations as e-h pairs at level centres within their structure called traps [4][5][6]. The trap characteristics can be expressed using trap parameters called activation energy E (eV), frequency factor s (s À1 ), and kinetic order b.…”

Progress in Synthesis and Photocatalytic Activity of MAl2O4(M=Mg, Sr, Ba) Based Photocatalysts

“…Among these spinel aluminates, MAl 2 O 4 (A = Mg, Sr, and Ba) has attracted extensive attention from researchers due to its excellent physicochemical properties make it can be used as long afterglow phosphor base materials, lightweight helmets, photoelectric devices, microwave dielectric capacitors, and high temperature windows, etc. (Han et al, 2018;Takebuchi et al, 2020;Basyrova et al, 2021;Kiryakov et al, 2021) Simultaneously, MAl 2 O 4 is a kind of environmental friendly material, in the photocatalytic field, especially in the degradation of organic dyes has a good application. (Wang et al, 2019a;Shifa Wang et al, 2020;Liu et al, 2022).…”
