ABSTRACT

The optically good superiority of NLO transparent 2 mol % of glycine doped L-Alanine sodium sulphate (LASS) single crystals were effectively developed by slow evaporation method. The crystalline nature of LASS and GLASS crystals were confirmed via XRD pattern and the diffraction peaks were well-indexed in the standard values. The FT-IR and FT-NMR spectroscopy studies were qualitatively established by the existence of all the functional groups through their atomic configurations in the molecular structure too. From the UV-Visible optical absorbance studies, the value of bandgap was determined at 5.22 and 5.51 eV for LASS and GLASS crystals sensibly. The SHG proficiency for GLASS crystal was measured using Nd: YAG laser and the value found to be 1.09 times superior to that of standard KDP material. The good structural, optical, thermal and SHG efficiency outcomes specified that the GLASS crystals might be very beneficial for NLO device applications.

摘要

采用慢蒸发法有效地开发了NLO透明的2 mol %甘氨酸掺杂L-丙氨酸硫酸钠(LASS)单晶的光学良好优势。LASS 和 GLASS 晶体的结晶性质通过 XRD 图案确认,并且衍射峰在标准值中具有良好的索引。FT-IR 和 FT-NMR 光谱研究是通过分子结构中的原子构型的所有官能团的存在定性建立的。根据紫外-可见光吸收研究,LASS 和 GLASS 晶体的带隙值确定为 5.22 和 5.51 eV。使用 Nd:YAG 激光测量 GLASS 晶体的 SHG 熟练度,发现该值比标准 KDP 材料高 1.09 倍。良好的结构、光学、
