LINEAR AND NON-LINEAR OPTICAL PROPERTIES OF MTC SINGLE CRYSTALS DOPED WITH ZNCL2

Abstract

Non-linear optics is playing a major role in the emerging photonic and optoelectronic technologies. Organic compounds possess a high degree of optical non-linearity than inorganic compounds, but they are thermally unstable. The need to make them thermally stable resulted in a new class of materials called semi organics. In the present study, Zncl2 doped Magnesium Thiourea Chloride (MTC) semi organic single crystals were grown by slow evaporation method. The grown crystals were characterized optically by recording UV-Vis spectrum. The optical band gap energy was determined using Tauc plot. The optical parameters like extinction co-efficient, complex optical dielectric constants and conductivity were determined by available methods. The grown crystals were examined by Kurtz-perry powder SHG method. The band gap energy values show that the grown crystals are dielectrics, and the SHG output of 532 nm was detected.
