Frequency doubling is one of the visually dramatic features among the nonlinear optical processes. In all materials, nonlinear effects of various types are observed at sufficiently high intensities. Nonlinear optical materials play a major role in the technology of photonics. Nonlinear optics is the study of interaction of radiation with matter in which certain variables describing the response of matter are not proportional to the variables describing the radiation. Nonlinear optical materials generating second harmonic frequency have a significant impact on laser technology, optical communication and optical storage technology.
Thermal properties of serine succinate crystal were evaluated with thermogravimetric, differential thermal and differential scanning calorimetric analyses. The second harmonic generation (SHG) of the grown crystal was confirmed by Kurtz powder technique. The mechanical hardness was estimated by Vickers’s micro hardness tester. Fluorescence study was also carried out for the grown materials.
The optical transparency and upper cut off value of UV transmission spectrum of SSA crystal were recorded. 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 cell parameters of the grown crystals were characterized by X-ray diffraction analysis.
Grown serine succinate crystals were subjected to various characterization techniques. In the present study single crystals of serine doped with succinic acid in different ratios have been grown by slow evaporation solution growth method. The overwhelming success of molecular engineering in controlling nonlinear optical properties in last decade has prompted better initiative in crystal engineering. Since amino acid exhibits nonlinear optical property, it is of interest to dope them in serine. Nonlinear optical single crystal of Serine Succinate (SSA) was grown from a mixed solvent of water, ethanol and methanol.
