Structural, Optical, Elemental and Thermal Characteristics of Pure and Magnesium Sulfate-Doped Growth Thiourea Crystals

Abstract

Abstract: The growth of single crystals of pure and magnesium sulfate (MgSO₄)-doped Thiourea (TU) was accomplished through solvent evaporation. The crystals were characterized using X-ray powder diffraction, FTIR, EDAX, UV-visible, and TG/DTA techniques. The MgSO₄-doped TU crystal exhibited excellent optical transmission across the entire visible range. The metal complexes of TU enhanced the lower cut-off wavelength by 14.85 nm compared to pure TU, which is an essential requirement for a nonlinear optical material.
