L-Alanine Cadmium Bromide (LACB) is a semi organic NLO crystal. There are many techniques to grow crystal at room temperature. In the present research work, the crystal has been grown by slow evaporation technique. Fourier transform infrared spectroscopic analysis was carried out to confirm the presence of different functional groups in the synthesized crystal. The powder X-ray diffraction study was used to observe the lattice parameters of the grown crystal. This XRD study shows that the grown crystal has orthorhombic in nature. The stability of LACB crystal has been strengthened by using Vicker’s micro hardness study. This test divulged that the hardening of the crystal increases with increase in load. From UV-Vis-NIR spectrum, the optical nature of the grown crystal was carried out. The grown crystal has lower cut off wavelength at 203 nm in this transmission spectrum
