Abstract

Single crystals of glycinium oxalate (GOX) were grown from aqueous solution by employing slow evaporation method at room temperature. Bulk crystals of good quality with dimensions 16 mm x 15mm x 4mm were grown by suitable growth conditions. The grown crystals were confirmed by X-ray diffraction studies and Fourier transform infrared spectra. Dislocation density of the grown samples was estimated using chemical etching technique. The UV-Vis transmittance spectrum indicates that the material has wide optical transparency (62%) in the entire visible region. The Kurtz powder test indicates the second harmonic generation efficiency of GOX is 75% that of KDP crystal. The mechanical strength of these crystals has been studied by using Vicker’s microhardness tester. The load independent hardness value is 42 kg/mm2
