Abstract
Single crystals of Glycinium oxalate (GLO) are grown by top seeded solution growth method. Characterization of the grown
crystal is done by CHN test and powder X-ray diffraction. UV-Vis-NIR, FTIR spectroscopic analysis, thermal studies by
TGA/ DTA and DSC, photoconductivity and photoluminescence studies, micro topography and chemical etching studies
have also been carried out. crystal has a wide transperancy window from 324nm to 2500 nm making it suitable for
applications in the whole region for higher harmonic generation and other optoelectronic applications. The good thermal
stability of the material ensures its suitability for possible applications in lasers, where the crystals are required to withstand
high temperatures. Z scan study under open aperture configuration illustrates the nonlinear optical behaviour of the grown
crystal. The comparatively high value of two photon absorptive index demonstrates that the GLO crystal has potential for
optical limiting applications.
