| Abstract: | A new semi organic Non-linear optical (NLO) crystal thiourea urea magnesium chloride (TUMC) was grown by slow evaporation technique at room temperature. Good quality single crystals were grown within 20?days. The FTIR spectrum of title compound was recorded and vibrational assignments were made. The recorded UV?Cvis spectrum shows the optical transmission property of the crystal. The Second harmonic generation (SHG) of TUMC crystal was tested by Kurtz?CPerry method using Nd:YAG laser and the result confirms that the grown crystal exhibits NLO property. To analyse the thermal stability of the crystal TG/DTA analysis were made. Detailed structural analysis of the compound is under progress. |
