Dosimetric characteristics investigation of ZnO/Ag/ZnO multilayer film for radiation applications

Abstract

The dosimetric properties of synthetic ZnO/Ag/ZnO multilayer film are investigated. The proposed dosimeter was prepared by radio frequency and direct current RF/DC sputtering and irradiated with X-ray doses up to 4 Gy. The properties of thermoluminescence (TL) such as glow curve, dose-response, homogeneity batches, sensitivity, minimum detectable dose (MMD), precision, kinetic parameters (activation energy E, frequency factor S), and percentage depth dose (PDD) were studied. The thin film appeared to have an excellent linear response, and the sensitivity was almost twice the commercial TLD. The readout of the homogeneity and PDD are the same properties of TLD-100. These desirable qualities demonstrated the versatility of this novel synthetic thin film in applications involving radiation detection.

Photoluminescence and thermoluminescence dosimetry properties of Ag/Y co‐doped ZnO nanophosphor for radiation measurements

“…Table 9 enlists the obtained results for E and S parameters. The results are consistent with the theory that deep traps are formed when silver ion is introduced [19,53].…”

“…The values at high doses are similar to the constant value $$$ \left({\delta}_S\right) $$$ as can be seen in Table 1. The behavior achieved in Figure 6 indicates a greater relative standard deviation at low doses, whereas it becomes essentially constant at high doses [35].…”

“…Figure 5 presents the suggested dosimeters with a golden card (homogeneity). The findings have shown that 73% of the batch was accepted to decrease TL calculation ambiguity [35,36].…”

“…where σT D is the sum of the standard deviations for a number of similar samples, ( δB D ) is the relative standard deviation at minmal doses and δ S ð Þ is the relative standard deviation linked to the dose D. The values at high doses are similar to the constant value δ S ð Þ as can be seen in Table 1. The behavior achieved in Figure 6 indicates a greater relative standard deviation at low doses, whereas it becomes essentially constant at high doses [35].…”

Designing High-Density of PbO-Enriched Telluro-Borate Glasses for Improved Radiation Shielding: A Comprehensive Study of Attenuation Parameters

“…These applications including (for example, but not limited), industrial, commercial and residential lighting, industrial and process equipment, chemical and petroleum processing, Aerospace, medical devices, electronic devices, and radiation shielding materials. 23,24 Traditional glasses, including those that are based on tellurite, silicate, borate and phosphates and frequently have diversified systems containing a variety of glass modifiers and intermediates, have indeed been examined in order to adjust their physical, electrical, mechanical and structural properties to diverse technical uses. [25][26][27][28][29][30][31] Boric oxide (B 2 O 3 ), which is introduced to glass as borates, is significant in the field of glass manufacturing since it possesses a combination of qualities that, if they were to be achieved by any other means, would either be extremely difficult or costly.…”
