- Abstract
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 H1NMR 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 Kurtz-Perry 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.
