This paper discusses the optical and mechanical properties of triglycine sulphate (TGS) and MgCl 2 added TGS single crystals (McTGS) grown from aqueous solution at room temperature using slow evaporation solution growth technique. The grown crystals were characterized by powder X-ray diffraction technique and the cell parameter values are found to be a = 9.405 Å, b = 12.623 Å and c = 5.721 Å; β = 110.347° with V = 637.001 Å3. UV-Vis-NIR study shows the direct type transition is involved in these materials and indirect, phonon energy gap of McTGS crystals have also been calculated, and these values are less than the TGS crystals. Refractive index and real and imaginary part of the dielectric constant have been discussed for grown crystals. The value of interband optical transition and oscillator energy has been determined by analyzing refractive index with incident energy. Vickers microhardness test was used to determine hardness number, fracture toughness, brittleness index, yield strength and types of crack formed in the crystals.
