Glass matrices of LiBO doped with Dy, Yb and Cu were synthesized by melt quenching technique using different concentration of copper nanoparticles. The study and analysis are centered in shielding radiation. The samples amorphous nature was corroborated by X-Ray diffraction (XRD) and nanoparticles size distribution was obtained by transmittance electron microscopy (TEM). Optical characterizations used were absorbance and photoluminescence emission (PL). Radiation shielding theoretical properties: mass attenuation coefficient (MAC), half value layer (HVL), tenth value layer (TVL), mean free path (MFP) and effective atomic number (Zeff) are obtained using Phy-X/PSD software and analyzed for future applications in radiation security.

含铜纳米颗粒Li2B4O7:Dy3+,Yb3+玻璃的屏蔽性能

采用不同浓度的铜纳米颗粒,通过熔融淬火技术合成了掺杂 Dy、Yb 和 Cu 的 LiBO 玻璃基体。研究和分析的重点是屏蔽辐射。通过 X 射线衍射 (XRD) 证实了样品的无定形性质,并通过透射电子显微镜 (TEM) 获得了纳米颗粒尺寸分布。使用的光学特征是吸光度和光致发光发射(PL)。辐射屏蔽理论特性:使用Phy-X/PSD软件获得质量衰减系数(MAC)、半值层(HVL)、十分之一值层(TVL)、平均自由程(MFP)和有效原子序数(Zeff)并进行分析用于辐射安全的未来应用。
