Abstract
Triglycine sulphate (TGS) is a ferroelectric crystal. The ferroelectric crystals find important applications in optoelectronics, photonics and used in the fabrication of high sensitivity infrared detectors at room temperature. TGS was synthesized by taking the AR grade Glycine (CH2NH2COOH) and concentrated sulphuric acid (H2SO4) in the molar ratio 3:1 respectively. The synthesized pure TGS is mixed with Ammonium dihydrogen Orthophosphate (ADP) in the molar ratio (9:1), (8:2) and (7:3) and the crystals were grown from aqueous solution by slow evaporation method at room temperature. The chemical composition of the grown crystals is confirmed by Energy Dispersive X-ray Analysis (EDAX). The solubility of grown crystals is determined using water as a solvent. The solubility curve shows that the TGS-ADP mixed crystal has higher solubility than the pure TGS. The grown crystals were crushed to a uniform fine powder and subjected to XRD analysis. Appearance of sharp peaks confirms the good crystalline nature. Using Scherer's equation particle size has been calculated. The Second harmonic generation efficiency is determined by Kurtz powder technique. The KDP crystal is used as a reference material, it is found that the relative SHG conversion efficiency of the grown crystals is greater than KDP sample which indicates the suitability of crystals for various applications. Optical transmission spectra are recorded for the crystals in the wavelength region 200 to 1100 nm using Perkin-Elmer Lambda 35 UV-Vis spectrophotometer. The electronic band transitions is studied from the plot of (αhv)2 versus photon energy (hv) and the band gap energy has been calculated. The functional groups have been identified by Fourier Transform Infrared spectroscopy (FTIR). The experimental results evidence the suitability of the grown crystals for optoelectronic applications.
