Abstract Strontium formate dihydrate single crystals have been grown by the slow solvent evaporation method and subjected to 8 MeV electron beam (EB) irradiation at different doses, viz. 1 kGy, 10 kGy, 50 kGy and 100 kGy. The irradiated crystals have been studied by various techniques such as FT-IR, Raman, and UV-Vis-NIR spectral analyses, powder, and high resolution X-ray diffraction, thermogravimetric analysis (TG/DTA) and second harmonic generation (SHG) measurements. The morphological features of the non-irradiated and irradiated crystals were analyzed by SEM and optical microscopy studies. It has been noticed that the SHG efficiency increases while the crystalline perfection and thermal stability of the irradiated crystals decrease with the increase of EB irradiation dose. The results indicate a significant overall tuning of physical properties of strontium formate dihydrate crystals due to irradiation.

8 MeV 电子束辐照 Sr(HCOO)2·2H2O 晶体的结构、光学、形态和倍频放大研究

摘要 甲酸锶二水合物单晶采用溶剂缓慢蒸发法生长，并在不同剂量下进行 8 MeV 电子束 (EB) 辐照，即。1 kGy、10 kGy、50 kGy 和 100 kGy。已通过各种技术研究了受辐射的晶体，例如 FT-IR、拉曼和 UV-Vis-NIR 光谱分析、粉末和高分辨率 X 射线衍射、热重分析 (TG/DTA) 和二次谐波生成 (SHG)测量。通过SEM和光学显微镜研究分析了未辐照和辐照晶体的形态特征。已经注意到，随着 EB 照射剂量的增加，SHG 效率增加，而被照射晶体的结晶完美度和热稳定性降低。
