In this study Bismuth-based nano-sized powders have been synthesized with Sol-Gel Pechini method by doping Er³⁺ and Yb³⁺. The microstructural and electrical properties were characterized and discussed in detail. The fcc cubic structures (δ-phase) were successfully obtained at 700, 750 and 800 °C. With the increase in sintering temperature, the range of cubic boundary values decreased. The lattice parameter decreased independently of the temperature with the increasing total dopant ratio. Total dopant rate should be minimum 18 mol%, respectively to obtain the δ-phase at 700 °C sintering temperature. On the other hand, dopant amounts of Er and Yb cations should be at a certain value. Total electrical conductivity was measured under various temperature conditions and doping concentration and Activation energies belong to samples are calculated. At the intermediate temperature zone (selected as 510 °C) the conductivity values were decreased with the increasing total dopant ratio. Conversely, the conductivity values were increased with the increasing total dopant ratio in the high-temperature region. Activation energies of cubic samples were measured as around ~0.9–1.3 eV.

在这项研究中，通过掺杂 Er ³⁺和 Yb ^{3+ ，}用溶胶-凝胶 Pechini 方法合成了铋基纳米尺寸的粉末。对微观结构和电性能进行了表征和详细讨论。在 700、750和 800 °C 下成功获得了fcc 立方结构（δ相）。随着烧结温度的升高，立方边界值的范围减小。随着总掺杂剂比例的增加，晶格参数与温度无关。总掺杂率应至少为 18 mol%，分别以获得δ相在 700 °C 烧结温度。另一方面，Er 和 Yb 阳离子的掺杂量应为特定值。在各种温度条件下测量总电导率，并计算出样品的掺杂浓度和活化能。在中间温度区（选择为 510 °C），电导率值随着总掺杂比的增加而降低。相反，在高温区域，电导率值随着总掺杂比的增加而增加。立方样品的活化能测量为约 0.9-1.3 eV。
