Physical, linear optical, dielectric spectroscopy and photon shielding competence of fabricated PVC (polyvinyl chloride) doped with xPbO nanoparticles (x = 0, 2.5, 5, 10, 15, and 25 wt%) have been investigated. The density of PVC is increased from 1.4451 to 2.1014 g cm⁻³ by incorporation 25 wt% of PbO. The optical band gap (E_gap) decreases from 5.14 to 4.54 eV for the direct transition and from 4.50 to 3.75 eV for the indirect transition as the concentration of PbO increases. Urbach energy (E_urbach) increased from 0.198 eV for the pure PVC sample to 0.673 eV for PVC loaded with 25 wt% of PbO. Refractive index (n) increased with the increase of PbO concentration. The less dielectric constant (ε′) values of all nanocomposites were obtained than that for pure PVC. Values of dielectric loss (tan δ) for all investigated samples decreases with increasing frequency up to 50 kHz and become constant for further frequency. Both linear (LAC) and mass attenuation coefficients (MAC) values of PVC were gradually increased by increase concentration of PbO while both half value layer (HVL) and relaxation length (RL) value were gradually decreased by increase concentration of PbO. Pure PVC with density (ρ = 1.4451 g cm⁻³) has neutron shielding characteristics better than that obtained for PVC/25 wt% PbO with higher density (ρ = 2.1014 g cm⁻³). The highest ∑_R is 0.06252 cm² g⁻¹ for pure PVC, and the lowest is 0.05003 cm² g⁻¹ for PVC/25 wt% PbO, in contrast. Finally, the obtained results confirm that the fabricated PVC-PbO nanocomposites can be applied in optical, electronic, and radiation shielding applications.

已经研究了掺杂有 xPbO 纳米粒子（x = 0、2.5、5、10、15 和 25 wt%）的制造 PVC（聚氯乙烯）的物理、线性光学、介电光谱和光子屏蔽能力。通过掺入 25 wt% 的 PbO ，PVC 的密度从 1.4451 增加到 2.1014 g cm ^-3。随着 PbO 浓度的增加，直接跃迁的光学带隙 (E _gap ) 从 5.14 eV 减少到 4.54 eV，间接跃迁从 4.50 eV 减少到 3.75 eV。Urbach 能量 (E _urbach ) 从纯 PVC 样品的 0.198 eV 增加到负载 25 wt% PbO 的 PVC 的 0.673 eV。折射率 (n) 随 PbO 浓度的增加而增加。介电常数（ε') 获得的所有纳米复合材料的值都高于纯 PVC 的值。所有研究样品的介电损耗 (tan δ) 值随着频率增加到 50 kHz 而降低，并在更高的频率下变得恒定。PVC 的线性 (LAC) 和质量衰减​​系数 (MAC) 值随着 PbO 浓度的增加而逐渐增加，而半值层 (HVL) 和弛豫长度 (RL) 值随着 PbO 浓度的增加而逐渐减小。具有密度 (ρ = 1.4451 g cm ^-3 ) 的纯 PVC 具有比具有更高密度 (ρ = 2.1014 g cm ^-3 ) 的PVC/25 wt% PbO 所获得的更好的中子屏蔽特性。最高∑ _R为 0.06252 cm ²  g ^-1对于纯 PVC，最低的是 0.05003 cm ²  g ^-1对于 PVC/25 wt% PbO，相比之下。最后，获得的结果证实所制备的 PVC-PbO 纳米复合材料可用于光学、电子和辐射屏蔽应用。
