Studies of Crystal Growth, Structural and Optical Properties of Glycinium-3-Carboxy-4-Hydroxybenzenesulfonate Single Crystal

Glycinium-3-carboxy-4-hydroxybenzenesulfonate(GCHBS),a new organic compound was synthesized and optical quality single crystal was grown by slow evaporation technique. The structure of grown crystal was elucidated by using single crystal X-ray Diffraction studies. The degree of sharpness and crystallinity was found from the Bragg peaks diffraction pattern. The presence of functional groups was confirmed fromthe FT-IRspectral analysis. UV–Vis transmission studies show that the grown crystal has optical transparency around 70%.The emission spectrum indicates that the GCHBS exhibits blue lighting emission sharply at 445 nm and it will be useful for fabricatingblue light emitting diodes.The thermal stability of grown crystal was studied from thermogravimetric and differential thermal analyses and found that the crystal is stable up to 235oC. The nonlinear absorption coefficient (β), nonlinear optical susceptibility (χ(3)) and nonlinear refractive index (n2) of GCHBS crystal were estimated by Z-scan technique.
