Advancing Green Photonic Materials: L-Serine Doped Creatininium Benzene Sulphonate Single Crystals

Doping organic crystals with amino acids to develop green materials utilizes the distinctive properties of amino acids to enhance both the sustainability and functionality of these materials. Green materials are crafted through environmentally friendly methods that minimize waste, emissions, and energy use, thereby reducing their overall environmental footprint. This doping process improves various properties of the organic crystals, including optical, electrical, and thermal characteristics, while also enhancing stability and mechanical strength. Amino acids can endow organic crystals with specialized functions, such as selective binding in sensors or improved catalytic activity, broadening their application potential. For this study, Creatininium Benzene Sulphonate single crystals were synthesized via slow evaporation at room temperature and doped with L-Serine. Structural characterization through XRD and FTIR confirmed the incorporation of the amino acid into the organic crystal. Structural refinement datas like FWHM,Crystallite size and lattice strain were obtained through Xpert Hi score Software .Thermal parameters, including Gibbs free energy, entropy, enthalpy, and activation energy, were assessed for both Creatininium Benzene Sulphonate and L-Serine-doped Creatininium Benzene Sulphonate using the Coats-Redfern method. The doping led to the material existing in four distinct phases, with enhanced catalytic activity at low temperatures verified by the Quantum Eyring Formula. This quantum-level analysis aids in designing more effective catalysts by revealing how they interact with reactants, optimizing catalytic processes. By understanding diffusion mechanisms alongside quantum tunneling, scientists can develop catalysts that enhance reaction rates, even at lower temperatures, by improving molecular diffusion. This dual focus on tunneling and diffusion allows for the creation of more selective and efficient catalysts, essential for green chemistry. Ultimately, these insights contribute to the development of sustainable materials with enhanced performance in various industrial applications. Optical properties such as refractive index, extinction coefficient, and bandgap were compared between L-Serine-doped Creatininium Benzene Sulphonate and the undoped crystal. Additionally, SHG values of the doped and undoped crystals were measured and compared to KDP Single Crystal. LDT values of the doped and undoped crystals were also compared with those of KDP and Urea single crystals. The results suggest that the optical properties, SHG, and LDT values of the L-Serine-doped crystal remain favorable, confirming also its suitability as a green material. This project aims to investigate how doping amino acids into Creatininium Benzene Sulphonate single crystals justifies their optical, thermal, and dielectric properties to determine their green material potential.
