Abstract

This work reports the synthesis and beta particle excited thermoluminescence (TL) characteristics of NaF and NaF:Tm phosphors synthesized via wet precipitation. The samples were subjected to thermal annealing at 750 °C for 5, 10, and 24 h in an air atmosphere. A sensitization effect is observed in repeated irradiation-TL readout cycles. The sensitization effect significantly decreases with increasing duration of thermal treatments and with decreasing irradiation dose. Furthermore, doping with Tm simplifies the shape of the glow curves in the region of maximum thermoluminescent intensity, located between 200 and 250 °C, a temperature range considered suitable for thermoluminescent dosimetry. The integrated TL is a linear function of the irradiation dose for the tested dose range (0.05 Gy–1.78 Gy). NaF is presented as a promising alternative to LiF for developing highly sensitive TL dosimeters, and it is concluded that NaF is a promising phosphor material, warranting further research into its dosimetric capabilities.

粒子辐照下NaF和NaF:Tm荧光粉的热释光特性。

本文报道了湿沉淀法合成的NaF和NaF:Tm荧光粉的合成和β粒子激发热释光特性。样品在750°C的空气气氛中进行5、10和24小时的热退火。在重复辐照- tl读出循环中观察到敏化效应。随着热处理时间的延长和辐照剂量的减小，增敏效果显著降低。此外，掺杂Tm简化了最大热释光强度区域的发光曲线形状，该区域位于200至250°C之间，这是适合热释光剂量测定的温度范围。综合TL是受测剂量范围（0.05 Gy-1.78 Gy）辐照剂量的线性函数。NaF被认为是一种很有前途的替代liff的材料，用于开发高灵敏度的TL剂量计，并得出结论，NaF是一种很有前途的荧光粉材料，值得进一步研究其剂量测定能力。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
