Single crystals of semi – organic nonlinear optical (NLO) Tris thiourea zinc cadmium sulphate (TTZCS) have been successfully grown from pH 3.5 solutions by slow cooling method. The thermal behaviour of the TTZCS crystal has been investigated from Thermo gravimetric, differential thermal and differential scanning calorimetric analysis. The micro hardness studies reveal the changes in the mechanical property of the crystals grown at pH 3.5. From Raman spectroscopic analysis, different modes of vibration due to various functional groups present in TTZCS have been observed. The morphologies of the crystals were analysed by Scanning electron microscope (SEM).
