Cu2+ and glycine doped L-arginine monohydrochloride monohydrate (LAHCl) single crystals were grown by slow solvent evaporation technique. The grown single crystals were confirmed by X-ray diffraction study and the interaction of dopants with LAHCl molecule was identified in Fourier transform infrared spectra. The crystalline perfection of pure and doped crystals was analyzed by high resolution X-ray diffraction studies. Vickers microhardness and UV-visible spectroscopy were carried out respectively to study the mechanical stability and optical transmittance of pure and doped LAHCl single crystals. He-Ne laser of wavelength 632.8 nm was used to measure refractive index and birefringence of grown crystals. The second harmonic generation efficiency was also measured for pure and doped LAHCl single crystals using Nd:YAG laser.
采用缓慢溶剂蒸发法生长了 Cu2+ 和甘氨酸掺杂 L-精氨酸盐酸单水合物（LAHCl）单晶。通过 X 射线衍射研究证实了所生长的单晶，并在傅里叶变换红外光谱中确定了掺杂剂与 LAHCl 分子的相互作用。通过高分辨率 X 射线衍射研究分析了纯晶体和掺杂晶体的晶体完整性。分别进行了维氏显微硬度和紫外-可见光谱研究，以研究纯和掺杂的 LAHCl 单晶的机械稳定性和光学透过率。使用波长为 632.8nm 的氦氖激光器测量了生长晶体的折射率和双折射。还使用 Nd:YAG 激光器测量了纯和掺杂的 LAHCl 单晶的二次谐波产生效率。
