“…From Figure 6 , it is clear that the nature of the glow curve depends on the type of fuel used during material preparation. The difference in the glow curve structure might be due to the creation of different trap location centers and defects during the material formation ( Abdoul et al, 2020 ). Mango leaves extract tends to create very less defects, and there were no prominent glow peaks where observed.…”

“…Though there are many metal oxides such as ZnO, CuO, MgO, TiO, CdO, etc., amongst magnesium oxide has unique properties such optical, electronic, thermal, mechanical, and chemical properties compared to other metal oxides ( Diachenko et al, 2016 ). It is a very stable and safe material to be used in different fields of applications and has high melting point, wide energy bandgap, high reactivity, and low heat capacity ( Abdoul et al, 2020 ; Fatiqin et al, 2021 ). In the present paper, we have made an effort to do a comparative study of MgO Nanostructures prepared using mango, neem, and papaya leaf extracts on structural, morphological, luminescence, and antibacterial studies.…”

Magnesium oxide nanostructured particles (NP) were prepared using a simple solution combustion technique using different leaf extracts such as Mangifera indica (Mango - Ma), Azadirachta indica (Neem—Ne), and Carica papaya (Papaya—Pa) as surfactants. The highly crystalline phase of MgO nanostructures was confirmed by PXRD and FTIR studies for 2 h 500°C calcined samples. To analyze the characteristics of obtained material–MaNP, NeNP, and PaNP for dosimetry applications, thermoluminescence (TL) studies were carried out for Co-60 gamma rays irradiated samples in the dose range 10–50 KGy; PaNP and NeNP exhibited well-defined glow curve when compared with MaNP samples. In addition, it was observed that the TL intensity decreases, with increase in gamma dose and the glow peak temperature is shifted towards the higher temperature with the increase in heating rate. The glow peak was segregated using glow curve deconvolution and thermal cleaning method. Kinetic parameters estimated using Chen’s method, trap depth (E), and frequency factor (s) were found to be 0.699, 7.408, 0.4929, and 38.71, 11.008, and 10.71 for PaNP, NeNP, and MaNP respectively. The well-resolved glow curve, good linear behavior in the dose range of 10–50, KGy, and less fading were observed in PaNP as compared with MaNP and NeNP. Further, the antibacterial activity was checked against human pathogens such as Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. A visible zone of clearance was observed at 200 and 100 μg/mL by the PaNP and NeNP, indicating the death of colonies by the nanoparticles. Therefore, PaNP nanomaterial is a potential phosphor material for dosimetry and antibacterial application compared to NeNP and MaNP.

Nanocrystalline boehmite material was synthesized using the hydrothermal method. Different annealing temperatures have been used to transform boehmite into different alumina phases to study the effect of different phase transitions on the thermoluminescence properties of alumina. XRD analysis was carried out to investigate the crystal structure of the different alumina phases. The thermoluminescence glow curves for different alumina phases showed different structures; however, the sensitivity was almost constant for all the phase transitions of alumina over the applied dose ranging from 0.55 to 330 Gy.

“…Generally, Li2B4O7 (LTB) as a borate compound is used in the dosimetric application but it does not comply with all the requirements so studies are still being continued to improve its properties [12][13][14][15][16][17][18]. Over the past few years, attempts have been devoted to TL properties of nanomaterials because of their exceptional TL response compared with their bulk counterparts [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The basic problem with the conventional TL materials is saturation of trapping states at high absorbed doses, which causes the TL response to become sub-linear in high radiation exposure.…”

Lithium tetraborate nanoparticles co-doped with various percentages of Cu and Mg impurities were synthesized through the combustion process. Scanning electron microscopy images along with X-Ray diffraction pattern confirmed the shape and structure of the products. The Williamson-Hall equation was used to measure the size of nanoparticles that resulted in approximately 47 nm for the crystallite size. The optical band gap of about 3.7 eV was obtained for the nanostructures from the UV-visible spectrum. Furthermore, the thermoluminescence features the samples under gamma irradiation were studied at ambient conditions. The highest thermoluminescence sensitivity achieved at 0.02 % wt Cu and 0.5 % wt Mg impurities simultaneously. The results show that the co-doped nanoparticles have a linear dose response up to an administrated dose of 30 kGy and about 10% of the thermoluminescence signal fades after 30 days of storage at room temperature.
