Using the sol–gel process, a series of Sr_2-xZnSi₂O₇:xGd (0.01 ≤ x≤0.11) samples was fabricated. Their crystal characteristics, surface morphologies, and spectral characteristics were analyzed using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL) spectroscopy. Upon 272-nm excitation, a prominent emission band appeared at 313 nm (⁶P_7/2 → ⁸S_7/2) in all the samples. The electron paramagnetic resonance (EPR) and PL analyses confirmed the presence of Gd³⁺ in the Sr₂ZnSi₂O₇ structure, where the Gd³⁺ ions occupied distorted Sr²⁺ sites in the host lattice. Additionally, three photon interaction parameters, namely the mass attenuation coefficient, effective atomic number, and effective electron density, were calculated within the 1 keV–100 GeV photon energy range for all the samples. These photon interaction parameters varied widely over the studied energy range. Particularly, the shielding effectiveness increased with increasing gadolinium concentration. These interaction parameters will be very useful for shielding applications against gamma-rays.

使用溶胶-凝胶过程中，一系列的Sr的_{2- X} ZnSi ₂ ø ₇：X的Gd（0.01≤  X ≤0.11）的样品被制造的。使用X射线粉末衍射（XRD），扫描电子显微镜（SEM）和光致发光（PL）光谱分析了它们的晶体特性，表面形态和光谱特性。在272 nm激发后，所有样品均在313 nm处出现明显的发射带（⁶ P _7/2  →  ⁸ S _7/2）。电子顺磁共振（EPR）和PL分析证实钆的存在³⁺在SR ₂ ZnSi ₂ ö_在图7的结构中，Gd ³⁺离子占据了主晶格中扭曲的Sr ²⁺位点。另外，在所有样品的1 keV–100 GeV光子能量范围内，计算了三个光子相互作用参数，即质量衰减系数，有效原子序数和有效电子密度。这些光子相互作用参数在所研究的能量范围内变化很大。特别地，随着effectiveness浓度的增加，屏蔽效果增加。这些相互作用参数对于屏蔽应用程序免受伽玛射线非常有用。
