Abstract
- The increasing use of thermoluminescence (TL) materials as radiation detectors with application in different areas of ionizing radiation has motivated research on new materials with adequate luminescent characteristics. In this work, experimental results gadolinium aluminate (GdAlO <subscript>3</subscript> ) analyzed by thermoluminescent phenomenon under beta irradiation effect are studied. To prepare GdAlO <subscript>3</subscript> powders the coprecipitation method was used. TL glow curve and other luminescent characteristics were analyzed using an automatic Lexsig Smart TL/OSL luminescent reader. TL glow curve showed four peaks with three prominent and well-defined peaks centered at 140, 230, and 270 °C. TL response as a function of beta radiation dose was linearity in the range from 1.1 up to 44 Gy. Kinetic parameters such as activation energy (E), frequency factor (s), and order of kinetics after the deconvolution of the TL glow curve were also determined using Chen's peak shape method. Experimental results show GdAlO <subscript>3</subscript> as a potential luminescent host material for TL studies.<br /> (Copyright © 2022 Elsevier Ltd. All rights reserved.)
