Analysis of Non-Linear Characterization for Optical Properties of Thiourea Tartarate

Abstract

In recent years, Analysis of  nonlinear optical  characterization of Crystals play an important role in the opto-electronics and frequency conversion device applications. The preset work aim to synthesis and grow Thiourea tartrate single crystals by slow evaporation solution growth technique for higher Non Linear Optical efficiency. Thiourea Tartrate single crystals have been grown by the slow evaporation method at room temperature using aqueous solution. The prepared crystal structural characterization, Thermal stability, Impedance properties and NLO studies were carried out with the help of powder X-ray diffraction analysis, thermogravimetric and Kurtz-Perry methods, respectively. The crystal was found to be in the mono crystal structure. The thermal studies of Thiourea tartrate reveals that at crystal is stable up to 208 ºC and shows absence of water molecules below 100 ºC. The NLO study measured with the help of Kurtz and Perry powder SHG technique and the results confirms that Thiourea tartrate has 1.6 times greater NLO efficiency than the KDP. Impedance analysis of the Thiourea Tartrate Sample has two semi circles which might be due to the contributions from grain and grain boundary. As grown Thiourea tartrate crystals can be used up to 2080C only for any applications and SHG results confirms the suitability of the crystals for NLO applications.
