Abstract
A new nonlinear optical urea based single crystal was successfully grown by using slow evaporation technique. The structure of the grown crystal has been confirmed by single crystal X-ray diffraction studies. The optical properties of grown crystal are analyzed by UV-Vis-NIR spectroscopy. Optical absorption spectrum confirms a wide optical transmission window for the sample. The powder second harmonic generation (SHG) efficiency has been confirmed by Kurtz and Perry technique. The SHG efficiency of the grown crystal is found to be 0.82 times that of standard KDP crystal. Thermal and mechanical behaviors of the grown crystal have been studied by thermo-gravimetric and differential thermal analysis (TG-DTA) and Vicker’s microhardness studies.
