摘要

通过缓慢蒸发溶液生长工艺合成并生长了非线性光学材料 L-Tryptophanium phosphite（LTP）。通过单晶 XRD、傅立叶变换红外光谱和 H1 NMR 光谱测量等特性分析，找到了晶体结构和官能团。通过紫外-可见-近红外光谱分析发现，该晶体在整个可见光区域都具有良好的透明度。利用 TG-DTA 分析评估了晶体的热性能，如稳定性和破坏性。晶体的硬度是通过维氏硬度研究确定的。KurtzPerry 方法用于研究晶体的非线性光学（NLO）特性。二次谐波发生（SHG）转换效率的良好数值使生成的晶体适用于频率转换。

Investigations on synthesis, growth and characterisations of a NLO material: L-Tryptophanium phosphite (LTP)

The nonlinear optical material L-Tryptophanium phosphite (LTP) was synthesised and grown by the process of slow evaporation solution growth. Characterisations like single crystal XRD, FT-IR, and H1 NMR spectral measurements were done to find the crystal structure and functional groups. The crystal was found to possess good transparency for the whole visible region from the UV-Vis-NIR spectral analysis. The thermal behaviour like stability and breakdown of the crystal were assessed using TG-DTA analyses. The hardness of the crystal was determined using Vickers micro hardness study. The KurtzPerry approach was used to study the nonlinear optical (NLO) characteristics of the crystal. A good value of conversion efficiency in second harmonic generation (SHG) makes the generated crystal suitable for frequency conversion.
