Samples from the PC-PBT/Ag nanocomposite have been exposed to gamma radiation with doses between 2 and 25 kGy. The resultant effect of gamma radiation on the structure and optical properties of PC-PBT/Ag nanocomposite has been investigated using TEM, XRD, FTIR and UV spectroscopy. The gamma irradiation with doses 5-25 kGy causes proper spreading of Ag nanoparticles in the PC-PBT matrix, resulted in an increase in the amorphous phase associated with a decrease in optical energy gap from 3.80 to 2.94 eV. Further, the nanocomposite has a response to color change as the color intensity increases from 0.64 to 4.94.

γ射线对聚碳酸酯-聚对苯二甲酸丁二醇酯/银纳米复合薄膜结构和光学性能的影响

来自PC-PBT / Ag纳米复合材料的样品已暴露于2至25 kGy剂量的伽马射线。使用TEM，XRD，FTIR和UV光谱研究了γ射线对PC-PBT / Ag纳米复合材料的结构和光学性能的最终影响。剂量为5-25 kGy的伽马射线辐照会导致Ag纳米颗粒在PC-PBT基质中适当散布，导致非晶相的增加，其光能隙从3.80 eV减小到2.94 eV。此外，随着颜色强度从0.64增加到4.94，纳米复合材料对颜色变化具有响应。
