Structural and mechanical properties of diglycine perchlorate single crystals

Abstract

Good quality diglycine perchlorate (DGPCL) single crystals were grown by slow evaporation solution growth method using the combination of glycine and perchloric acid in the ratio of 2:1. Single crystal X-ray diffraction and mechanical characterization of the grown single crystals of diglycine perchlorate were analyzed in this article. Lattice parameters, space group and crytal system were found from single crystal X-ray diffraction analysis. All the cell parameters and space group are in a good agreement with the reported values. Mechanical properties, such as Vicker's microhardness number, work hardening index, standard hardness value, yield strength, fracture toughness, brittleness index and elastic stiffness constant values, were determined using Vicker's microhardness tester.

Third order nonlinearity examined by pulsed and CW lasers: an organic urea barbituric acid (UBA) single crystal for optical limiting application with DFT study

“…The reason for increasing the elastic stiffness constant (C 11 ) value of the UBA crystal is due to the binding forces between the atoms and ions of urea barbituric (UBA) which are quite strong. Furthermore, the yield strength (σ y ) values represent the maximum stress a material may experience without causing plastic deformation or shape variation [56]. Table 7 lists the current mechanical properties compared to a few nonlinear optical (NLO) crystals (inorganic, semi-organic, and organic).…”
