Growth, spectral, optical, laser damage threshold and DFT investigations on 2-amino 4-methyl pyridinium 4-methoxy benzoate (2A4MP4MB): A potential organic third order nonlinear optical material for optoelectronic applications

摘要

Graphical abstractDisplay OmittedHighlights?2A4MP4MB exhibits high optical transmittance and thermally stable up to 424?K.?The grown 2A4MP4MB exhibits self-defocusing and saturation absorption behavior.?Optical limiting properties of 2A4MP4MB have been studied.?Large laser damage threshold value of about 3.61?GW/cm2has been observed.AbstractIn present investigation, single crystals of organic charge transfer complex, 2-amino-4-methyl pyridinium-4-methoxy benzoate (2A4MP4MB) was grown by controlled slow evaporation solution growth technique using methanol as a solvent at room tempe
