Abstract: In this study, the crystal growth and characterization of pure and strontium (Sr)-doped zinc thiourea chloride (ZTC) crystals have been investigated. Single crystals of ZTC and Sr-doped ZTC with doping concentrations of 2 mol% were successfully grown by using the slow evaporation technique at a constant temperature of 35°C. The structural properties of the grown crystals were examined through powder X-ray diffraction (XRD) techniques to determine unit cell dimensions and analyze crystalline phase variations. Optical transparency was studied using UV-Visible spectroscopy, which revealed that the grown crystals exhibited wide transparency across the visible region. Fourier Transform Infrared (FT-IR) spectroscopy was employed to identify functional groups and bonding characteristics. Nonlinear optical (NLO) properties were assessed through second harmonic generation (SHG) studies using the Kurtz-Perry powder technique with an ND-YAG laser at 1064 nm in Q-switched mode. The results indicate that Sr doping significantly influences the structural, optical, and NLO properties of ZTC crystals, enhancing their potential for photonic and optoelectronic applications. This comprehensive analysis highlights the effectiveness of Sr as a dopant in improving the material's performance, making it a promising candidate for advanced nonlinear optical technologies.
