Abstract

This work presents the synthesis and characterization of nanostructured Fe-doped ZrO₂ as a novel shielding material against ionizing radiation, particularly gamma rays. Through a simple, environmentally friendly, and cost-effective hydrothermal synthesis technique, two samples of Fe-doped ZrO₂ nanoparticles were synthesized. The incorporation of iron ions into the ZrO₂ lattice aims to enhance the material's radiation attenuation capabilities by leveraging the synergistic effects of the host matrix and dopant. Comprehensive characterization techniques, including XRD, SEM, and EDX, were employed to investigate the structural, morphological, and elemental properties of the synthesized nanoparticles. The results revealed successful doping of iron ions into the ZrO2 lattice, accompanied by the formation of oxygen vacancies to maintain charge neutrality. The higher doping concentration sample exhibited larger crystallite sizes, reduced lattice distortions, and lower dislocation densities, suggesting enhanced structural integrity. Furthermore, the radiation shielding properties of synthesized Fe-doped ZrO₂ composites were evaluated using the experimental measurements, Monte Carlo simulation, and theoretical calculations. The experimental measurement shows that the linear attenuation coefficient of prepared composites over the interval of 0.662 MeV and 1.332 MeV decreased from 0.430 ± 0.014 cm⁻¹ to 0.301 ± 0.007 cm⁻¹ (for Fe1 composite) and decreased from 0.443 ± 0.013 cm⁻¹ to 0.302 ± 0.006 cm⁻¹ (for composite Fe2). The measured linear attenuation coefficient was found to be in agreement with the simulated and theoretically calculated data.

纳米工程铁掺杂ZrO2：绿色水热合成的新型可持续伽马射线屏蔽材料

这项工作提出了纳米结构铁掺杂ZrO2的合成和表征，作为一种新型的电离辐射屏蔽材料，特别是伽马射线。通过一种简单、环保、经济的水热合成技术，合成了两个fe掺杂ZrO2纳米颗粒样品。将铁离子掺入ZrO2晶格的目的是通过利用宿主基质和掺杂剂的协同效应来增强材料的辐射衰减能力。采用XRD、SEM和EDX等综合表征技术对合成的纳米颗粒进行了结构、形态和元素性质的研究。结果表明，铁离子成功掺杂到ZrO2晶格中，同时形成氧空位以保持电荷中性。高掺杂浓度的样品显示出更大的晶体尺寸、更少的晶格畸变和更低的位错密度，表明结构完整性增强。通过实验测量、蒙特卡罗模拟和理论计算，对合成的掺铁ZrO2复合材料的辐射屏蔽性能进行了评价。实验测量表明，制备的复合材料在0.662 MeV和1.332 MeV范围内的线性衰减系数从0.430±0.014 cm−1下降到0.301±0.007 cm−1 （Fe1复合材料），从0.443±0.013 cm−1下降到0.302±0.006 cm−1 （Fe2复合材料）。实测的线性衰减系数与模拟和理论计算的数据吻合较好。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
