Glycine zinc sulphate salt was synthesized and the solubility and metastable zonewidth were estimated from the aqueous solution. Single crystals of glycine zinc sulphate were grown by solvent evaporation method from aqueous solution. Grown crystals were characterized by X-ray diffraction and FT-IR spectral analyses. The range and percentage of optical transmission was ascertained by recording UV-vis-NIR spectrum. Thermal properties of the crystal were investigated by thermogravimetric analysis. Microhardness study was carried out on (01-1) face of the grown crystal. Its powder second harmonic generation efficiency was measured using Nd:YAG laser and the value was observed to be 0.7 times that of potassium dihydrogen orthophosphate.
合成了甘氨酸硫酸锌盐，并从水溶液中估算了其溶解度和介稳区宽度。采用溶剂蒸发法从水溶液中生长出甘氨酸硫酸锌单晶。通过X射线衍射和傅里叶变换红外光谱分析对生长的晶体进行了表征。通过记录紫外-可见-近红外光谱确定了光透射的范围和百分比。通过热重分析研究了晶体的热性质。对生长晶体的（01-1）面进行了显微硬度研究。使用Nd:YAG激光测量了其粉末二次谐波产生效率，观察到该值是磷酸二氢钾的0.7倍。
