Abstract
The Semi-organicPottasium Thiourea Chloride (KTC) was grown by slow evaporation
method. The structural studiesofKTC single crystal was carried out by using powder X-ray.Thermal
Analysis was carried out by Perkin-Elmer thermal analyzer (STA 409 PC) and the DTA trace
indicates a strong endothermic peak at 210 °Cdue to the melting of the crystal. Dielectric studies
and Complex Impedance analysis made by E4990A impedance analyzer.Kurtz Perry method was
employed to find Second harmonic Efficiency of grown KTC single crystals.Good transparency,
thermal stability and NLO test suggests Pottasium Thiourea Chloride single crystals can be used for
optical applications.
