摘要

这项工作的目的是研究xY2O3-15Li2O-15ZnO-5Bi2O3- (65-x)P2O5玻璃的屏蔽能力、光学质量和物理特性。当钇量从0.0 mol.%增加到3.0 mol.%时,密度由2.9407 g/cm3增加到3.3694 g/cm3。氧堆积密度(OPD)与氧摩尔体积(OMV)相对于y离子mol%的增长相反。采用物理- x程序和蒙特卡罗模拟来评估玻璃样品的显著快中子辐射衰减特性。结果表明,Y2O3的加入降低了半值/弛豫长度,增加了快速去除截面(FCS)。在对核辐射的总屏蔽能力方面,Y3.0玻璃样品在中子辐射衰减方面优于Y0.0玻璃样品。在玻璃体系中加入Y2O3提高了其偏转中子辐射的能力。所得的紫外-可见-近红外吸收光谱用于估计带隙EOPT的光能,用于光学研究。采用Tauc图确定EOPT;直接读数介于4.197和3.779 eV之间。发现随着Y2O3用量的增加,带隙能量下降,折射率和乌尔巴赫能量增加。计算了电子极化率、摩尔极化率和摩尔折射率。建议用掺钇磷酸盐玻璃作为屏蔽材料。

Impact of yttrium on the optical and neutron radiation shielding properties of bismuth-lithium-zinc-phosphate glasses
The goal of this work is to examine the shielding capabilities, optical qualities, and physical characteristics of xY2O3-15Li2O-15ZnO-5Bi2O3- (65-x)P2O5 glasses. The density measurement grew from 2.9407 to 3.3694 g/cm3 as the yttrium quantity raised from 0.0 mol.% to 3.0 mol.%. Oxygen packing density (OPD) grew in the opposite manner as oxygen molar volume (OMV) with respect to Y-ions mol%. The PHY-X program as well as Monte Carlo simulations were employed for assessing the glass samples' significant fast nuetron radiation attenuation characteristics. The results concluded that the inclusion of Y2O3 decreased the half-value/relaxation length while increasing the fast removal cross section (FCS). In terms of total shielding capabilities against nuclear radiation, the Y3.0 glass sample outperformed the Y0.0 glass sample in neutron radiation attenuation. Adding Y2O3 to the glass system improves its ability to deflect neutron radiation. The resulting UV–VIS–NIR absorbance spectra were used to estimate the optical energy of the band gap EOPT for the optical investigations. Tauc's plots were used to determine the EOPT; direct r eadings fall between 4.197 and 3.779 eV. It was discovered that as the Y2O3 quantity raised, the band-gap energy fell while the refractive index and Urbach energy increased. Electronic polarizability, molar polarizability, and molar refraction were also computed. Yttrium doped phosphate hlasses was suggested as a shielding material.
