Crystal Growth and Characterization of Single Crystals of Glycine doped with Ammonium Bicarbonate (GABIC) Crystal

Abstract

At room temperature, a suitable conventional technique is used in the formation of a semi-organic single crystal of glycine that had been combined with ammonium bicarbonate (GABIC). Spectroscopic analysis is used to study the generated single crystal of ammonium bicarbonate complexed glycine. Based on the results of single crystal X-ray diffraction examinations, the monoclinic system is determined. The FT-IR spectral research was the method that led to the identification of the many functional groups that are presented in GABIC. Both the UV-visible spectrum and the fluorescence spectrum provide information on the optical and electrical characteristics of the formed crystal, respectively. The optical band gap has been calculated to be 4.49 eV after taking into account the UV absorption curve. A number of optical parameters, such as the extinction coefficient and the reflectance, were also measured and calculated. Vickers microhardness experiments were used to determine the mechanical stability of the generated crystal, and the results showed that the crystal clearly belonged to the soft material group. In order to quantify the material's hardness number (Hv), Meyer's index (n), yield strength (σy), elastic stiffness constant (C11), brittle index (Bi), and fracture toughness (Kc) a Vickers microhardness test was performed on one of the as-grown hard crystals (Hv). Constant frequency measurements of the formed crystal's dielectric constant and dielectric loss were taken. By using a scanning electron microscope, we were able to figure out the morphology of the material's surface. The Nd: YAG laser has been used to assess the damage threshold energy required to cause permanent damage (1064 nm). With the use of the open aperture Z-scan method (Nd: YAG, 532 nm, 9 ns), we are able to determine that the nonlinearity coefficient (β) is 0.95 1010 m/W, which is the outcome of an effective two-photon absorption phenomena. With a fluence threshold of 3.26 1012 W/m2, the GABIC's consequent optical limiting characteristic makes it a promising option for use in optical limiting devices. The creation of GABIC was shown by these experiments, and Glycine was found to be a critical factor in the observed modifications to the crystals' spectral, optical, and mechanical characteristics.
