A set of glasses of composition (ZnO)0.3-(V2O5)0.6–x-(B2O3)0.1-(Na2O)x with x = 0.1, 0.15, 0.2 and 0.3 were prepared and their non-crystallinity were confirmed. Density and molar volume were found to decrease with increasing Na2O concentration. Using Phy-X/PSD and XCOM softwares, radiation-shielding efficiency was determined by estimating mass attenuation coefficient, linear attenuation coefficient, effective atomic number, half value layer, tenth value layer and mean free path of glasses for gamma energy from 0.005 to 15 MeV. Obtained shielding parameters led to propose the glasses for γ-ray shielding at lower energy regime. Conductivity variation with temperature was analyzed using Mott’s small polaron hopping model and activation energy was determined. It was found to decrease with increasing Na2O content both at high and low temperature. The density of states at Fermi level was determined using Mott’s and Greave’s variable range hopping (VRH) models at low temperature.

Na2O掺杂锌硼钒酸盐玻璃的伽马射线屏蔽特性和电学性能

制备了一组组成为 (ZnO) 0.3 -(V 2 O 5 ) 0.6–x -(B 2 O 3 ) 0.1 -(Na 2 O) x的玻璃,其中 x = 0.1、0.15、0.2 和 0.3,它们的非-确认了结晶度。发现密度和摩尔体积随着 Na 2的增加而降低氧气浓度。利用Phy-X/PSD和XCOM软件,通过估算玻璃的质量衰减系数、线性衰减系数、有效原子序数、半值层、第十值层和伽马能量从0.005到15的平均自由程来确定辐射屏蔽效率。兆伏。获得的屏蔽参数导致提出了在较低能量状态下用于γ射线屏蔽的玻璃。使用莫特的小极化子跳跃模型分析电导率随温度的变化并确定活化能。发现在高温和低温下均随着Na 2 O含量的增加而降低。费米能级的态密度是使用 Mott 和 Greave 的低温可变程跳跃 (VRH) 模型确定的。
