摘要

In this article, we discuss the preparation of organic aloe vera amino acid added Curcumin crystal, grown from slow evaporation solution growth method from an aqueous solution. The Single crystal X-ray diffraction study determined that the crystal belongs to the monoclinic system with the space group P2/n. The crystalline nature of the Aloe vera Curcumin crystal was further analysed using the Powder XRD method. FTIR spectroscopy analysis confirmed various functional band frequencies of AVC crystal. UV–Visible spectral study was conducted to determine the crystal’s optical transparency, cut-off wavelength, and band gap energy, revealing transparency across the entire visible-NIR spectrum. Sharp emission peaks in the photoluminescence spectrum indicated ultraviolet (UV) emission. A Laser induced damage threshold study was performed using an Nd: YAG laser at an operating frequency of 1064 nm. Microhardness property of AVC was evaluated upto 100 g indentation load and results are analysed. Additionally, third-order nonlinear optical properties such as nonlinear refractive index, nonlinear absorption coefficient, and third-order nonlinear susceptibility of the grown AVC crystal were calculated using the Z-Scan technique.
