Abstract

Materials with favorable nonlinear optical properties receive more attention in advanced optical technology. This study aims to design, synthesize, and characterize a novel single crystal with exceptional third-order nonlinear optical (NLO) properties. Utilizing the solvent evaporation method a single crystal of 1-methyl-2[2-(4-ethylphenyl)vinyl]pyridinium iodide (EMPI) was obtained with high crystallinity. The crystal structure of the EMPI was determined through Single Crystal X-ray diffraction (SCXRD), confirming its atomic arrangement and its purity was verified using the CHN elemental analysis. Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectroscopy confirmed the molecular composition (C₁₆H₁₈) and functional groups of the EMPI. Hirshfeld surface analysis was employed to elucidate the intermolecular interactions in the EMPI crystal. The optical characteristics of the EMPI crystal were evaluated through the UV-Vis-NIR spectroscopy and Photoluminescence (PL) analysis, revealing its remarkable 80% transparency in the visible range and suitability for green light-emitting diodes. AFM and etching analysis affirmed that EMPI crystal has a smooth surface with fewer dislocations. The Z-Scan analysis demonstrates the third-order nonlinear optical performance and the optical limiting capabilities of the EMPI crystal, highlighting its potential as a key material for advancing optoelectronic devices and optical protection systems.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
