ABSTRACT: Single crystals of L-lysine added Potassium Bromide were grown by slow evaporation technique at room temperature. The crystalline nature of the grown crystal wasconfirmed using powder X-ray diffraction technique. Single crystal X-ray diffraction patterns were recorded for the structural conformation and it was found to be cubic. The UV –VIS- NIR Spectrum of the grown crystals shows less optical absorption and good transmittance in the entire visible region enabling its use in optical applications. Vickers micro hardness test was carried out to analyze the mechanical property of the grown
