Abstract
A Schiff base (LS2) compound is synthesized via a reaction of a hot ethanolic solution of (3-ethoxy salcyaldehyde) and a hot ethanolic solution of amine(methyl-4-amino benzoate). The LS2 compound is characterized via 1H and 13C NMR spectra, Mass spectrum, and FT-IR spectrum. We observed multiple diffraction patterns of a cw 473 nm laser beam from the LS2 compound caused by spatial self-phase modulation (SSPM). The nonlinear refractive index (NLRI) of the LS2 compound is estimated at the high-power input of the laser beam and found equals to 5.387 × 10-7 cm2/W. The Z-scan techniques are used to estimate the NLRI and found equals to 0.12 × 10-7 cm2/W. The all-optical switching (AOS) effect can be seen when 473 nm is used as the controlling beam and 532 nm is used as the controlled beam.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
