ZnO multilayer film for radiation applications (original) (raw)

Journal of physics, 2022

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.
