Abstract

Nonlinear optical single crystal of Serine Succinate (SSA) was grown from a mixed solvent of water, ethanol and methanol. Since amino acid exhibits nonlinear optical property, it is of interest to dope them in serine. The overwhelming success of molecular engineering in controlling nonlinear optical properties in last decade has prompted better initiative in crystal engineering. In the present study single crystals of serine doped with succinic acid in different ratios have been grown by slow evaporation solution growth method. Grown serine succinate crystals were subjected to various characterization techniques. The cell parameters of the grown crystals were characterized by X-ray diffraction analysis. FT-Raman spectral studies were carried out on the SAA grown material to confirm the synthesized compound and the functional groups of serine succinate single crystal were identified from FTIR analysis. The optical transparency and upper cut off value of UV transmission spectrum of SSA crystal were recorded. Fluorescence study was also carried out for the grown materials. The mechanical hardness was estimated by Vickers’s micro hardness tester. The second harmonic generation (SHG) of the grown crystal was confirmed by Kurtz powder technique. Thermal properties of serine succinate crystal were evaluated with thermogravimetric, differential thermal and differential scanning calorimetric analyses. The SEM studies were also reported.

Highlights

Semi-organic crystals have been proposed as new candidates with interesting nonlinear optical properties as they possess high thermal and mechanical stability compared to organics [2] [3]
The same procedure was adopted by taking serine and succinic acid in methanol (SSAM), serine and succinic acid in ethanol-methanol (SSAEM) and serine and succinic acid in ethanol-water (SSAEW) in the ratio 1:2
The single crystal X-ray diffraction data confirms that the grown crystal is monoclinic and the space group is P

Summary

Introduction

Nonlinear optical materials generating second harmonic frequency have a sig-. Semi-organic crystals have been proposed as new candidates with interesting nonlinear optical properties as they possess high thermal and mechanical stability compared to organics [2] [3]. Crystallization of organic materials for use in nonlinear optical devices is of great interest due to their high nonlinearity, high flexibility in terms of molecular structure, high optical damage threshold and low cost [4]. In many organic nonlinear optical materials there is a solid frame work of conjugated π electrons along with weak Vander Waals and hydrogen bonds which are responsible for most of their nonlinear optical properties. Metal complexes like organic compounds have several advantages as far as their third-order nonlinear optical properties are concerned [5]
